2. AUTO / MANUAL MODE

A. AUTO MODE

Your iS3 Drive is equipped with its own internal counter. When the Auto Mode isselected, the Drive uses this counter to determine when to initiate various RunPatterns that are pre-programmed in AUTO GROUP. This mode can also be usedfor grouping different Drive commands in one.

AUT 01 : Auto Mode (Factory Default Setting : Auto A)Range : Auto A, Auto B

[AUTO A] Mode will allow the Drive to operate automatically followed by its pre-programmed time schedule. According to this time schedule, 8 different steps ofFrequency Commands , Directions of motor, Run Time, and Transient Times can beinitiated with only a single multifunction input contact closure(I/O 01 to I/O 06).[AUTO B] Mode can be also used to program up to 8 different steps as Auto A.However, to switch from one step to another, an external contact closure to one ofthe multifunction input terminals is required.

AUT 02 : Way Select (Number of Sequence Selection)(Factory Default Setting : 1)

Range : 1 – 7 Your iS3 can have total of 7 whole sequences(Way) for the Auto Mode. Each

sequence can have up to 8 different steps(each step includes separate FrequencyCommands, Directions of motor, Run Time, and Transient Times). In thisparameter, operator can select the number of sequence to program.

WAY_M 0 1 1 0 0 1 1

WAY_H 0 0 0 1 1 1 1

(0: open, 1: closed)]

AUT 03 : Steps (Way X) (Factory Default Setting : 1) Range : 1 - 8

This parameter determines a total number of Steps per Way to be used for the AutoMode. The value X depends on the value of AUT 02. For example, if the AUT 02 isprogrammed to be 3, then the display will read Steps (Way 3). If the total number ofsteps for the Way 3 is 7, then AUT03 should be set to 7.

AUT 04 : Way1 / 1f (Factory Default Setting : 0.00 Hz) AUT 04, AUT 08, AUT 12, AUT 16, AUT 20, AUT 24, AUT 28, AUT 32 :

WayX / Yf Range : 0 - 400 Hz

Here, the symbol X is the value of AUT 02, Y is the value of AUT 03, and f meansfrequency command. This parameter is used to set a frequency reference for StepYth of Way Xth. Refer to Example given.

AUT 05 : Way1/ 1t (Factory Default Setting : 0.0 seconds) AUT 05, AUT 09, AUT 13, AUT 17, AUT 21, AUT 25, AUT 29, AUT 33 :

WayX / Yt Range : 0 - 6000 seconds

Here, the symbol X is the value of AUT02, Y is the value of AUT03, and thesymbol t stands for Transient Time that takes to reach one step to another.This value can also be used as Acceleration and Deceleration time.

AUT Steps (Way1) 03 1

AUT Way1 / 1f 04 0.00 Hz

AUT 06 : Way1 / 1s (Factory Default Setting : 0.0 seconds) AUT 06, AUT 10, AUT 14, AUT 18, AUT 22, AUT 26, AUT 30, AUT 34 :

WayX / Ys Range : 0 - 6000 seconds

Here, the symbol X is the value of AUT 02, Y is the value of AUT 03, and the symbol s stands for Steady State Time of the drive during its run. This parametervalue will determine for how long the drive will operate in a set Step speed.

AUT 07 : WayX / Yd (Factory Default Setting : Forward) AUT 07, AUT 11, AUT 15, AUT 19, AUT 23, AUT 27, AUT 31, AUT 35 :

WayX / Yd Range : Forward, Reverse

Here, the symbol X is the value of AUT 02, Y is the value of AUT 03, and thesymbol d stands for the motor direction. This parameter will determine the directionof the motor for each Steps.

EXAMPLE :A company wants to use an iS3 drive for their chemical mixer application. Themixer must rotate in at various speeds in alternating directions depending upon settime periods. When initiated, the drive should accelerate within 2 minutes in theclockwise direction to reach 20Hz of speed, and run for 1 hour. Then, the drive itmust accelerate to 40 Hz in 2 min. in counter-clockwise direction, and run for 1hour. After that, the drive must ramp down to zero speed in 2 minutes decelerationtime.The above application can operate in either AUTO A or AUTO B.

FUN 62 : SS blk. Time - Speed Search Block TimeRange : 1 ~ 10 seconds (Factory Default Setting : 0.3)

This function is used to initiate the automatic restart mode after an InstantaneousPower Failure of over 15milliseconds in duration. As the drive resets itself from IPF,it waits a moment(FUN 62) before it starts to search for the current speed of thecoasting motor. Once the current speed of the motor is determined, the drive thenaccelerates(FUN 60, FUN 61) to the previous set frequency reference.Gate Blocking Time and Acc/Dec. time for the speed search mode must be set whileconsidering the inertia moment and the magnitude of torque demand of the load.

This function can be used to bring the motor to a quick stop without the use ofDynamic Braking Resistors. FUN 37 sets the starting frequency where the DCInjection begins. FUN 38 is the time between the DC Injection command and theactual desired moment of DC injection output. FUN 39 is the total braking time.FUN 40 is the level of DC Injection Voltage Output(% of rated). The DC InjectionBraking can be selected by selecting DCBR in FUN 15. Also one of the multi-function input terminals can be used to trigger the DC Injection Braking bydesignating a terminal to be EXT_DCBR. (see 15.

This function is used to compensate for excessive motor heat which is generatedduring low frequency operation. This is especially true if the capacity of the motor islower than that of the inverter. To prevent the motor from overheating, the ETHlevel must be set according to the provided formula.

ETH level(%) = K * (Motor rated current / Inverter rated current) * 100( K = 1.0 for 50Hz Input Power, K = 1.1 for 60 Hz Input Power)

Once the ETH level is found, then the motor type must be determined. There are twoelectronic thermal characteristics, one is a ‘General’ pertaining to a standard ACinduction motor, the other is ‘Special’ for a special motor containing a blower.Once the correct values are programmed, the drive will determine the ETH time foreither the General or Special motor per below.

For General MotorETH time = 60*((Motor rated current * Drive output freq. * ETH level) /(Drive rated output current * 60 Hz * 100))

FUN 50 : Stall Prevention Level (Factory Default Setting : 150%)Range : 30 ~ 150%

These functions are used to prevent the motor from stalling by controlling theinverter output frequency until the motor current level decreases below the StallPrevention Level.Once the motor current level falls this value of FUN 50, then the drive will increaseits output frequency to its set point.

" ACCIf the output current of the drive has reached the stall prevention level duringacceleration, the drive will stop accelerating until the current level is reduced belowFUN 50 before it resumes acceleration to a set frequency command.

" STEADYIf the output current of the drive has reached the stall prevention level during steadyspeed running period due to load fluctuation, the drive will then reduce its outputfrequency until the output current level is reduced below FUN 50. The drive willthen increase its output frequency to a set frequency command.

" DECIf the DC BUS voltage reaches the O.V. fault level(790~810 VDC for the 400VACclass, 395~405 VDC for the 200VAC class) during deceleration, the drive will stopfurther deceleration.

8. ENERGY SAVING

FUN 14 : Energy Saving Level (Factory Default Setting : 80%)Range : 50 ~ 100%I/O 01 ~ I/O 06 :Multifunction Input (P1~P6 : ENY_SAV)

There are several ways to control the flow of fan or pump as inlet vanes and outletdamps. Due to ‘Affinity Law’, these methods are not energy efficient. In case ofoutlet damp, there is only 5 % drop of input power demand when the flow reducesfrom 100 % to 80 %. In HVAC fan application, ‘Energy-Output Speed’ relation isnot linear but square. The required power by the load is proportional to the square ofthe motor speed. For example, a pressure sensor detects the air pressure level, andsends the signal to pressure-current transducer, which then feeds 4 to 20mA signal tothe blower drive.When the air pressure in the air duct decreases, by means of pressure sensor, acontact closure at designated multifunction input terminal can initiate the EnergySaving mode of the drive. This results the iS3 to reduce its output voltage to thevalue set in FUN 14 and still maintain the same thermal state. This also results inless energy consumption.

The drive command frequency in ‘DRV 00’ can be set via keypad by selecting‘KEY’ in FUN 02. The value of ‘DRV 00’ will be limited depending on the valueMaximum Frequency set in FUN 04. Generally, the maximum frequency can beset either to the maximum motor output speed or to the value, which the operatordesires . The Base Frequency is the motor rated speed in Constant Torque range.This base frequency value should not be set higher than that of FUN 04.If the base frequency is set at 60 Hz and the maximum frequency is set at 120 Hz,the motor will run up to 60Hz in Constant Torque mode and up to 120 Hz inConstant Horsepower mode. The Start Frequency set in FUN 06 provides theinitial frequency output of the drive. Setting this value too high can result inincreased starting output voltage demand which might cause ‘excessive outputcurrent’.Note : Whenever max. frequency setting has changed, all of the above parametersmust be modified for correct motor operation.

In order for the drive to receive frequency reference from an external source, the‘FUN 02’ must be set to ‘Terminal’. The ‘FUN 24’ is used to select the analogfrequency reference method. If 0 ~ 10 VDC signal is the source of reference, then‘Voltage’ should be selected. If 4 ~ 20 mA signal is the source of reference, then‘Current’ should be selected. When both of the signals are used, then‘Voltage+Current’ should be selected.

*** When PI control function is selected, the value in ‘FUN 02’ will be ignored.Also, the 0~10 VDC signal becomes the frequency reference, and 4 ~ 20 mAbecomes the feedback signal(also refer to PI control section).

The ‘Analog filter gain setting’ in ‘FUN 25’ can be adjusted to set theresponsiveness of the drive output. For example, to obtain a faster response, the gainin ‘FUN 25’ is set to lower value and vice versa.

FUN V - I mode 24 Voltage

FUN Filter gain 25 50 %

FUN Analog gain 26 100 %


65

The ‘Analog speed gain’ in ‘FUN 26’ is used to set the correct ratio of the analoginput signal and its maximum frequency reference of the drive. For example, if thedrive needs to accept +5 VDC analog signal as its Max. frequency reference insteadof +10 VDC. By setting ‘FUN 26’ to ‘50%’ the drive will calculate its Max. analoginput by ’10 VDC * FUN 26(0.5) = 5 VDC’. This setting will prepare the drive tounderstand +5 VDC input signal as its Max. frequency reference.

If ‘FUN 26’ is used to set the ratio between the ‘Maximum analog input signal’ andthe ‘Maximum frequency reference’, ‘FUN 27’ is used to set the ratio between theMinimum analog input signal and the Minimum frequency reference. For example,if FUN 27 is set at 50 % and the analog input signal is 0 VDC, then the drive willcalculate its Min. frequency reference (Maximum frequency * FUN 27) whichbecomes half of the set Maximum frequency.

The value set in ‘FUN 28’ will determine the Analog Input Vs. FrequencyReference slope to be either a positive slope or a negative slope linear ratio. Whenset to ‘Direct’, the analog command signal(0-10VDC or 4-20mA) representsincreasing positive slope. When set to ‘Invert’, then the signal(0-10VDC or 4-20mA) represents decreasing negative slope.

I/O 01 ~ I/O 06 : Multifunction Input Terminal selection (SPD_L, SPD_M, SPD_H)

I/O 12 ~ I/O 18 : Step Frequency Setting

The drive can be pre-programmed to follow up to 7 different steps of frequencyreference. Each of the steps can be initiated by shorting ‘multifunction input’terminals to the ‘common’ terminal. Each step frequency setting is designated to oneof the 7 steps(via SPD_L, SPD_M, SPD_H).Example) Let’s say the drive needs to have 7 different step speed reference values.We would like to program the terminals P1 through P3 to become SPD_L, SPD_M,and SPD_H. The drive must be programmed as below:I/O 01 = SPD_L (Set P1 to SPD_L)I/O 02 = SPD_M (Set P2 to SPD_M)I/O 03 = SPD_H (Set P3 to SPD_H)This is actually a binary number. If SPD_L = 0, SPD_M = 1, and SPD_H = 0(terminal P1 = open, P2 = closed, and P3 = open), then this represents the step2(010)in binary form.The speed reference value set in each of the I/O 12 ~ I/O 18 will be the drive speedreference for that particular step.

The Keypad displays the drive frequency output to the motor once the RUNcommand is initiated. When the speed feedback card is installed, the frequencydisplay is the actual motor speed. However, when the drive is running in the openloop(no feedback card) condition, the frequency output displayed on the keypaddoes not necessarily mean the exact motor speed, but the output frequency of theinverter.! When the drive is not in RUN mode, the frequency display indicates the

programmed frequency reference.

!!!! SPD_L(WAY_L), SPD_M(WAY_M), SPD_H(WAY_H)

In Manual ModeAny of the three ‘Multi-function Input Terminals(P1 through P6)’ can be designatedas 3 separate switches used to select one of the seven different frequency steps.These (SPD_L, SPD_M, and SPD_H) are really in binary code. Let’s say P1, P2, P3and P4 terminals were programmed(via I/O 01 ~ I/O 06) to be SPD_L, SPD_M,SPD_H and JOG respectively. When the P1 is open, P2 is open, and P3 is closed,then this means that SPD_L is zero binary bit, SPD_M is zero binary bit, andSPD_H is one binary bit. The highest bit of three binary bits is ‘SPD_H’, and thelowest bit is ‘SPD_L’. Therefore, above terminal inputs will represent ‘001’ inbinary, which is ‘frequency step #4’.When the drive receives this ‘001’, it searches for the preprogrammed stepfrequency reference #1(I/O 15). However, these step frequency references are set inI/O 12 ~ I/O 18. Refer to Section 10 Application Note 1.

!!!! JOG (GO_STEP)

In Manual ModeOne of the multifunction input terminals can be programmed to become a JOGswitch by setting a input terminal to ‘JOG(GO_STEP)’. This can be done bychoosing one of P1 ~ P6(I/O01 ~ I/O6) to the above value. For information on theJOG function, please refer to ‘JOG’ section.

In Auto ModeWhen one of the multifunction input terminals is configured to be used as‘GO_STEP’, the drive will proceed to next preprogrammed step within chosen Way(Sequence) whenever this terminal is closed. This function is to be used in ‘AUTOB’ mode only.In ‘AUTO A’, the drive will automatically proceed to next step following the timesequence programmed. However, In ‘AUTO B’, the drive must have this‘GO_STEP’ input terminal closed in order to proceed to the next step.


76

!!!! CEL_L, CEL_M, CEL_H

In Manual Mode, the iS3 can be programmed to have up to 7 different Accel/Deceltimes by configuring three of six terminals to CEL_L, CEL-M, CEL_H (Lowest bit,Middle, Highest bit). The Accel/Decel times are set in I/O 19 ~ I/O 32.

!!!! SS(HOLD_LAST)

In Manual ModeThe Speed Search mode can be activated via an external multi-function inputterminal. When operating the motor with a high inertia load, or switching the motorinput power from High-Line(Commercial Line) to the drive, the drive outputfrequency should approach the actual motor speed in order to protect the driveinverter from in-rush current. Along with I/O 10(AUX), this Speed Search mode canbe initiated during the By-pass mode. Please refer to Application Note 3.

In Auto ModeWhile the drive is running in Auto A or Auto B mode, the operator might find itnecessary to hold on to present step(or speed) before the drive proceeds to next step.A ‘multi-function input’ terminal can be configured as ‘HOLD_LAST’ in order tohold the present step as long as the terminal is closed.

!!!! EXT_DCBR

The ‘D.C. Injection Braking’ can be applied when a multifunction terminalconfigured as ‘EXT_DCBR’ is closed to common. This DC Injection can be appliedat zero speed drive output frequency. When used with the ‘RUN’ command, thedrive can immediately engage its motor to start rotating without being pulled in thereverse direction. The total amount of DC Injection Voltage can be programmed via‘FUN 38’. The value of FUN 38 is the maximum voltage the drive will put out tothe motor during the DC Injection command.

Example)If a multi-function input terminal ‘P4’ is configured as ‘EXT_DCBR’, then the ‘DCInjection Braking’ can be applied by closing terminal ‘P4’ while the motor sits withzero frequency. Let’s say the motor is connected to the load with some weight, andit’s holding its position by means of a mechanical break. In order to prevent the‘Sliding Back’ of the motor at the time of the break release, the drive can apply DCinjection breaking voltage to hold the load for a short period of time. While the DCinjection is active, one can initiate the ‘Forward Run’ command at the same time ofthe break release. This will result in the motor rotating with no or minimal ‘SlidingBack’ effect.

!!!! EXT_TRIP

The iS3 drive can be configured to have ‘E-Stop’ via an external terminal byprogramming one of the multi-function input terminals. For example, if ‘P4’terminal is configured to be ‘EXT_TRIP’, the drive will decelerate as configured in‘FUN 15’ whenever ‘P4’ is closed. Once this ‘EXT_TRIP’ is triggered, the drivemust be RESET and the RUN command must be re-initiated to restart the drive.This switch is ‘Normally Closed’ during normal operation and ‘Opened’ during faultcondition.

The iS3 drive can operate 2 different motors at different capacities at a time. Forexample, an application needs one 10 HP motor to lift a load which requires a FWDand REV torque boost, and it also needs to one 5 HP motor to traverse along the rail.Instead of having two different sized drives, a 10 HP iS3 can be used to operate bothof the motors. Along with ‘FUN 66 ~ FUN 74’ configuration for the second motor.

When one of the multi-function terminals(I/O1 to I/O6) is set to ‘ALT_MOTOR”(alternate motor), multi-function input terminal can be used to run a secondary 5HP traverse motor when closed to common. When the terminal set to‘ALT_MOTOR” is closed to CM terminal the inverter changes its output to FUN 66~ FUN 77. This is an economic way of controlling 2 motors for two separate motorsequences.

16. MULTIFUNCTION OUTPUTS

The iS3 drive is equipped with 3 Open Collector Outputs(Q1, Q2, and Q3) and aAuxiliary Relay Output(AUX) terminals. They all can be configured to be used to asdrive status output terminals via I/O 07 ~ I/O 10 in the I/O Group.

!!!! FST_LODuring acceleration, deceleration, and constant speed conditions, the iS3 cangenerate an output signal via the multi-function output terminals whenever its outputfrequency is below the value in ‘I/O 36’. (If an operator wants to have a method tosee if the drive is generating output frequency less than the ‘Frequency SteadyLevel’ value for his particular application, this can be done by selecting the‘FST_LO’ and setting the frequency level in ‘I/O 36’).I/O 36 : Frequency Steady Level (Factory Default Setting : 0.5 Hz)Range : 0.5 ~ 400 Hz

[Q1 is configured as FST_LO]

!!!! FST_HIThis function is used as ‘FST_HI’, and the output signal is generated when the driveoutput frequency is higher than the frequency steady level value set in ‘I/O36’.I/O 36 : Frequency Steady Level (Factory Default Setting : 5 Hz)Range : 0.5 ~ 400 Hz

! FDT_HIIf the operator needs to know whether the drive is operating above a certainfrequency level, the ‘FDT_HI’ can be selected to use one of the multi-functionoutput terminals to generate a signal as long as the drive output speed is abovethe set ‘Frequency Detection Level’. A ‘Frequency Detection Bandwidth’ canalso be set for better steady output signal.I/O 37 : Frequency Detection Level (Factory Default Setting : 60 Hz)Range : 0 ~ 400 HzI/O 38 : Frequency Detection Bandwidth (Factory Default Setting : 1 Hz)Range : 0 ~ 30 Hz

[Q3 is configured as FDT_HI]

! FDT_PULSEThis function is used basically the same way as ‘FDT_HI’. Instead of generating acontinuous signal throughout until the frequency falls below the set point in ‘I/O37’, when selected, it generates 100 ms pulse as the output frequency reaches thevalue of ‘I/O 37’ during acceleration and deceleration.

!!!! FDT_BANDIf this function is selected, the drive no longer looks for the detection level but onlythe ‘Frequency Bandwidth’. For example, if the output frequency of the drive fallswithin its programmed bandwidth(I/O38), then the designated multi-function outputterminal will generate the signal. This signal will be generated regardless of whetherthe output frequency of the drive has reached its reference frequency.

!!!! O.L.(Overload Signal)When the output current has reached the overload warning level set in ‘FUN 51’ foroverload duration time set in ‘FUN 52’, the drive will generate a signal through oneof the ‘O.L.’ designated multi-function terminals. This overload signal willdisappear once the current output level falls below the value of ‘FUN 51’ and heldfor more than half of the time set in ‘FUN 52’.

!!!! A_WAY_END (sequence endpoint flag)A multi-function output terminal for ‘A_WAY_END’ will generate a pulse signal(100ms) whenever the drive has reached the last step of its Auto Sequence it wasrunning. For example, if the drive parameter ‘WAY 1’ is programmed to have up to8 different steps in Auto A mode, then the drive output terminal ‘A_WAY_END’will generate a pulse signal whenever the drive reached its final step 8.

26. V/F PATTERN

FUN 08 : Volts per Hertz Pattern Select (Factory Default Setting : Linear)Range : Linear, 2.0, User, Auto Boost

Depending on the applications, different Volt/Hertz patterns can be selected. Forexample, In HVAC application, ‘2.0’ pattern can be selected since ‘2.0’ is wellsuited for Variable Torque applications.

Linear [Constant Torque Applications]This pattern is best suited for ‘Constant Torque’ applications like ‘Conveyors’. This‘Linear’ pattern has a V/F ratio that is constant throughout the entire frequencyrange up to the drive maximum frequency.

2.0 [Variable Torque Applications]The V/F ratio in this mode is no longer a constant. Rather the ratio is composed ofthe square and cube powered ratio characteristics. This makes ‘2.0’ mode suitablefor Variable Torque applications such as FAN and PUMP.

User [Custom Pattern]The ‘User’ Pattern can be used for special purpose applications. There are 4 V/Fpoints that can be programmed between the starting frequency and the basefrequency.

FUN 16 : User V/F Set Frequency 1f (Factory Default Setting : 60 Hz)Range : 0 ~ 400 HzFUN 17 : User V/F Set Voltage 1v (Factory Default Setting : 100%)Range : 0 ~ 100 %

As above, the rest of V/F points can be set up to 4th V/F point frequency andVoltage.

These ‘FUN 16 ~ FUN 23’ are valid only when the ‘User’ is selected in ‘FUN 08’.If only 2 points between the start frequency and the base frequency are needed, then3f, 3v, 4f, and 4v should be set at rated voltage and frequency.

Auto [Auto Boost]The ‘Auto Boost’ can be used in high starting torque applications such as crane andhoist. This pattern will automatically boost the output torque by sensing its loadcurrent demand; as a result, the drive will have the higher torque characteristic at thelow output speed range than in the Linear pattern mode. The amount of torque boostis determined automatically by the drive calculations. This ‘Auto’ pattern should notbe used in multi-motor applications.

27. UPLOAD / DOWNLOAD FROM KEYPAD

FUN 80 : Upload Parameters to keypad (Factory Default Setting : No)Range : Yes, NoFUN 81 : Download Parameters to keypad (Factory Default Setting : No)Range : Yes, No

By setting ‘FUN 80’ to ‘Yes’, all drive data, including fault history, will beuploaded to the EPROM of the keypad. This can be a useful way to store drivestatus at specific time or it can even be used to trouble-shoot in conjunction with theLG engineering office.By setting ‘FUN 81’ to ‘Yes’, all drive data stored in the keypad will be downloadedto the drive. This can be useful option when coping set of the parameter from a driveto other drives.

28. OTHER FUNCTIONS

FUN 13: Maximum Drive Output Voltage (Factory Default Setting : 100%)Range: 0-110%

Inverter output voltage can be adjusted by this function. This function is useful whenrated motor voltage is lower than the rated inverter output voltage. 110% meansover-modulation in PWM causing little bit higher output voltage compare to 100%of rated output voltage.

FUN 48: Fault Output Relay mode selection (Factory Default Setting : Retry 0)Range: Retry 0, All trips, LV+Retry 0, LV+All trips

The Fault Output Relay (30A, 30B, 30C) operates when a fault occurs and it can be

VI. CHAPTER SIXMAINTENANCE AND TROUBLE SHOOTING

1. MaintenanceSV-iS3 Series can be influenced by temperature, humidity, and vibration. To avoid anypossible uncertainty, the drive must be maintained properly by certified personnel.

2. Precaution! Only certified personnel familiar with the equipment are permitted to install, operate

and maintain the drive.! Observe the Charge LED on the drive to be sure of complete power dissipation.! The output voltage of your SV-iS3 drive can only be measured by a rectifier voltage

meter(such as RMS meter). Other instruments such as digital meter will readincorrect value due to the high switching PWM frequency.

3. Routine Inspection! Check Input-Line Voltage to the drive for any fluctuation.! Check the Cooling Fan.! Check for any physical vibration to the drive.! Check the temperature for any overheating.

4. Visual Inspection! Any loosen screw, nuts, or rust?

→ Tighten up or change.! Any deposit of dust in the AC Drive or Cooling Fan?

→ Clean the dust off or any conductive fines.! Any disconnection of connector from PCB?

→ Tighten up the connector.! Any sound from the Fan?

→ Replace.
