Safety Information Description
Compared with power frequency running
The inverter is a voltage source type machine and the output voltage is PWM waves including harmonics. Therefore, the temperature rise, noise and vibration of the motor will slightly increase compared with power frequency running.
Constant-torque low-speed running
When the inverter drives common AC induction motor to run at a low speed for a long term, the output torque maybe reduced due to the heat dissipation effect of the motor. If it is required to run at a low speed and constant-torque for a long term, a variable frequency motor must be used.
Electronic thermal protection value of motor
When using an adaptive motor, the inverter could perform thermal protection on the motor. In case that the motor is not matched with the inverter in rated capacity, the protection threshold value must be adjusted or other protection must be taken for guaranteeing safe running of the motor.
Running over 50Hz
In case that the motor runs at the frequency over 50Hz, in addition to increase of the vibration and noise of the motor, the applied

Note: The usage and working conditions needs to be considered when selecting brake
resistor. The following is a description of brake resistor selection:
(1)Brake Resistor Calculation When the output current equals half the rated current of the motor, the same braking
torque can be obtained as the rated torque of the motor,so the rough calculation of brake
resistor is:𝑅𝑅𝐵𝐵 = 2∗𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀
,𝑈𝑈𝐷𝐷 is brake voltage,𝐼𝐼𝑀𝑀𝑀𝑀 is motor rated current,to ensure that the inverter is not damaged, the minimum value of the brake resistor is 𝑅𝑅𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 when the current flowing through the brake resistor is motor rated current. When selecting the resistance of the brake resistor, it must not be less than the below value. 𝑅𝑅𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 = 𝑈𝑈𝐷𝐷
𝐼𝐼𝑀𝑀𝑀𝑀
According to the above description, the selection range of brake resistor is:𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀
< 𝑅𝑅 ≤ 2∗𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀
(2)Brake Resistor Power Calculation
The power of brake resistor:𝑃𝑃0 = 𝑈𝑈𝐷𝐷2
𝑅𝑅
The brake resistor power is mainly determined by the brake utilization rate ED%. Because the braking time of the system is relatively short, the temperature rise of the braking resistor is not enough to achieve a stable temperature rise.So the principle for determining the brake resistor capacity is to minimize the brake resistor capacity if the temperature rise of the brake resistor does not exceed its allowable value (i.e. the rated temperature rise),The rough algorithm is as follows:
𝑃𝑃𝐵𝐵 = 𝜆𝜆 ∗ 𝑃𝑃 ∗ 𝐸𝐸𝐸𝐸% = 𝜆𝜆 ∗ 𝑈𝑈𝐷𝐷2
𝑅𝑅∗ 𝐸𝐸𝐸𝐸%,
𝜆𝜆 = 1 − |𝑅𝑅−𝑅𝑅𝐵𝐵|𝑅𝑅𝐵𝐵
is brake resistor derating coefficient(Normally select 16)。

3.7 EMC Precautions
The inverter can produce electromagnetic interference,this interference will affect automation devices and instruments probably.Correct installation can reduce electromagnetic nosie of devices and improve the interference resistance . To ensure that the inverter can run normally for a long time, please refer to the following installation description.
3.7.1Field Wiring
Equipment classification:When multiple equipment is mounted in a common enclosure,such as inverter, filter, PLC and detection instrument . According to the ability in emitting electromagnetic noise externally and bearing noise, the devices are classified into strong-noise devices and noise-sensitive devices. The same type equipment shall be installed in the same area. The different type equipment shall be kept distance of 20cm or above. It is suggested to isolate different areas spatially through metal shells or grounding partition plates in the enclosure.
Wiring in the enclosure: Main power cables and signal cables are generally arranged in the enclosure. The signal cables are easy to be interfered by the main power cables and then cause equipment trip. So, the signal cables and the main power cables are supposed to be distributed in different areas, not in the same cable tray, it is prohibited to arrange parallel wiring and alternate wiring of the signal cables and the main power cables in the close distance of 20cm, and the signal cables and the main power cables shall not be bound together either. If a signal cable must go across a power cable, a 90-degree angle shall be maintained between the signal cable and the power cable. Inputand output cables of the main power shall not be alternately arranged or bound together.
3.7.2 Noise Suppression and Grounding
The inverter must be grounded reliably in the operating process. Grounding is conducted for the safety of equipment and people and furthermore provides a simplest and most effective method with lowest cost for solving EMC problems, thereby deserving priority in consideration.
Shielding cables shall be adopted for all control terminals of the inverter. The shielding layer is grounded nearby the inlet of the inverter. Cable clamps are adopted for
- 24 -
NVF5 Series User Manual Chapter 3 Installation and Wiring
grounding to realize 360-degree circular connection. It is prohibited to twist the shielding layer before connecting it to the inverter in case that the shielding effect is lowered greatly or even lost.
A shielding cable or an independent cable tray shall be adopted between the inverter and the motor. One end of the shielding layer of the motor cable or the metal shell of the cable tray is connected nearby the inverter, and the other end is connected with motor shell.
The grounding cable shall be as short and thick as possible so as to lower grounding impedance, grounding cables shall be far away from the input side and the output side of noise-sensitive devices.
3.7.3 Leakage Current Suppression
Leakage currents include line leakage currents and grounding leakage currents. The magnitude of a leakage current depends on distributed capacitance of the system in the wiring process and the carrier frequency of the inverter. The leakage current can be effectively lowered by reducing the carrier frequency and using motor cables as short as possible. When the motor cable is long (50m or above), an AC output reactor or a sine wave filter shall be installed at the output side of the inverter; when the motor cable is longer, it is supposed to install one reactor at a certain distance.
Two classification and expression modes of leakage currents are: Grounding leakage current: means the leakage current flowing through a common
grounding cable. It may flow into the inverter as well as other devices through the grounding cable. The leakage current may cause malfunction to a residual-current circuit breaker, a relay or other devices.
Lines leakage current: means the leakage current flowing through distributed capacitors among the cables at the input side and the output side of the inverter. The magnitude of the leakage current is relevant to the carrier frequency of the inverter, the length of the motor cable and the sectional area of the cable. The higher the carrier frequency of the inverter, the longer the motor cable and the larger the sectional area of the cable, the larger the leakage current is.

6.2.7 Process PID Main Frequency Setting
Process PID control is a common method of process control. Through proportional, integral and differential calculation of the difference between the feedback signal and the target signal of the controlled variable, the output frequency of the inverter is adjusted by the closed-loop, so that the controlled variable can be stabilized at the target value;
When the PID is used as reference, if the PID forbidden is set at the same time (terminal function 44), the system will switch to the F9.29 standby channel for regulation.

The speed loop PI parameters are divided into two groups: low speed and high speed,
when the running frequency is smaller than F3.03-Switch Frequency1,speed loop PI
regulated parameters are F3.01 and F3.02,when the running frequency is greater than
F3.06-Switch Frequency2 ,speed loop PI regulated parameters are F3.04 and F3.05. The speed loop dynamic response characteristics of vector control can be adjusted by
setting the proportion and integration time of the speed regulator. Increasing proportional gain and reducing integration time can speed up the dynamic response of speed loop. However, if the gain is too large or the integration time is too small, the system will oscillate.

● Speed Regulator、Torque Regulator Mode Selection
Speed / Torque Mode is switched by parameter F3.00 ,also it can be switched by
setting DI1 ~ DI and HDI terminals(DI function 38). ● Torque Control Reference Torque Control Reference is set by parameter F3.19. When the torque reference is given byAI1、AI2、HDI,the final torque reference is:
AI output percentage of analog curve AI(pulse of HDI curve) × motor rated torque.
AI analog curve、pulse of HDI curve:refer to 6.2.3 Analog Main Frequency Setting (AI1、AI2 setting) 、 6.2.4 Pulse Main Frequency Setting;
When the torque reference is positive,the inverter run forward,when the torque
reference is negtative,the inverter run reverse. ● Speed→Torque switch point In order to avoid the system sudden skip in the start-up process, the inverter firstly
complete the start process in the speed mode, and switches to the torque control mode when reaching the switching point;
This method can effectively solve the problems of insufficient starting torque and sudden skip of starting torque in torque mode.
● Torque control Accel./Decel. time Torque control Accel. Time F3.24 means acceleration time of torque reference from 0
to rated torque of motor,torque control Decel. Time F3.25 means deceleration time of torque reference from rated torque of motor to 0.
● Forward/Reverse speed limit value in torque control mode Used to set up the positive or reverse maximum operating frequency of the inverter
under the torque control mode. In torque control mode,If the load torque is less than the output torque of the motor,
the speed of the motor will rise continuously. In order to prevent the mechanical system from flying accidents, it is necessary to limit the maximum speed of the motor.

The integral regulator of the current loop does not use integral time as dimension, but directly sets integral gain.
If the PI gain of the current loop is too large, the system may oscillate. Therefore, when the current oscillates or the torque fluctuates greatly, the Proportional gain or the Integral gain can be reduced manually.
6.7 OverCurrent Stall Protection If the current exceeds 150% action current of overcurrent stall (1.5 times of motor
rated current) during the running process, the overcurrent stall will take effect and the output frequency will begin to decrease, until the current returns below the overcurrent stall point, the frequency will start to accelerate up to the target frequency, and the actual acceleration time will be increased automatically. The greater the overcurrent stall gain, the stronger the overcurrent stall, the faster the output frequency drops.

Figure 6-9-1 Motor Overlaod Inverse Time Curve
When the overload protection gain FE.01 is set to 100%, the inverse time limit characteristic of motor overload protection is defaulted to: motor overload fault will occur after running continuously for 10 minutes under the condition of 150% motor rated current; motor overload fault will occur after running continuously for 80 minutes under the condition of 110% motor rated current.
● Motor Overload Early Alarm
Motor overload early alarm function is used to output warning signal to control system through DO before motor overload fault protection. The early alarm coefficient is used to determine the level of early alarm before motor overload protection, and the larger the value, the smaller the early alarm amount.
When the cumulative output current of the inverter is greater than the overload time (the cumulative value of the inverse time curve of motor overload protection) × the overload alarm level FE.03 of the motor, the DO will output the effective signal of motor

A.8 Network Wiring A.8.1 Topology structure
RS-485-Modbus repeater is not configured. There is a trunk cable which is directly connected with all devices (daisy-chained) or connected through short branch cable.
Trunk cable, also known as Bus, may be very long. The termination resistor must be connected at the each end of the network cable. Also the repeater can be used among multiple RS-485 Modbus. And each slave address in the network is unique, which is the basis for guaranteeing Modbus serial communications. A.8.2 Length
End-to-end length of the trunk cable must be limited. Maximum length is related to Baud rate, load quantity on the cable (specification, capacitance, or characteristic impedance) and daisy chain and network configuration (2-wire or 4-wire system).
Branches must be short and cannot exceed 20m. If multi-port splitter with n branches, the maximum length of each branch must be restricted to 40m divided by n. A.8.3 Grounding Mode
“Network Common” circuit (common end of the signal and optional power supply) must be directly connected to PE ground. It’s better that the whole Bus is grounded in a single point. Usually, this point is optional on the master or its splitter. A.8.4 Cable
Modbus cable on the serial link must be shielded. At each end of the cable, shield must be connected to the PE ground. If the connector is used in this end, the connector housing should be connected to the cable shielding layer. RS485-Modbus must use a pair of lines and the third line (for common end).
For RS485-Modbus, cable of diameter wide enough must be selected to allow the use of maximum length (1000m). AWG24 can meet the needs of Modbus data transmission.。
A.9 Definition of Communication Exception Code When the corresponding error message is detected in the communication process,
the lower machine (i.e., CPU ) will be position “1” of the function code, and feedback corresponding error code (exception code), to recognize the current error for the host computer. The corresponding definitions are shown in Table A.6.

Parameter Change Properties(Changeable or Not/Change Condition) ○ Parameters are changeable in Stop or Running status
◎ Parameters are changeable in Ready status and Inchangeable in Running status.
● Parameters are actual detection value and inchangeable;(Inverter has
checked the modification attributes of each parameter,which helps user avoid misoperation)
2、“Parameter decimal” Most of them are decimal(DEC),If the parameter starts with
"0x", it is represented as Hexadecimal.(Such as 0x0000),When editting parameters , the
range of partial bits can be Hexadecimal.(0~F)。
3、“Default Value” It is represented when resetting parameters to factory default, the value of the parameter is refreshed; but the actual detection value or record value will not be refreshed.
4、For better protecting parameters setting, inverter provides password protection function.See 4.3 Keypad Password Setting.
