2 INSTALLATION AND DIMENSION 2.1 Environmental Requirements The design of the cabinet to house the CNC unit, the keyboard panel and the LCD display is the responsibility of the machine tool builder. The cabinet must be constructed and the unit installed in an environment satisfying the following conditions Ambient Temperature

When operating: 0o C to 45o C. When storing or transporting the system: -20o C to 55o C.

Temperature Variation Maximum: 1.1o C/minute. Humidity Normally: 80% RH or less (Relative Humidity). For short period: maximum 95% RH. Vibration When operating:


2 - 2

2.3 Thermal Design for the Cabinet The cabinet for the control unit must be a closed structure, and the temperature rise within the cabinet must be 10o C or less than the ambient temperature. When designing a metal cabinet for a CNC unit, two factors must be considered, which are the heat source and the radiation area. The heat source is from the CNC unit itself, users cannot do anything to reduce it. Therefore, the one thing that the user can do in controlling the temperature rise is the radiation area. The allowable temperature rise inside a metal cabinet can be estimated as follows: 1. With a cooling fan, the allowable temperature rise is 1o C/6 W/1 m2. 2. Without a cooling fan, the allowable temperature rise is 1o C/4 W/1 m2. This means that a cabinet with a radiation area of 1 m2 and a cooling fan will have an internal temperature rise of 1o C when a heating unit of 6 W (4W without a cooling) is inside the cabinet. The radiation area of a cabinet is the entire surface area of the cabinet minus the area contacting the floor. Example 1 (with a cooling fan): A cabinet has a 2 m2 radiation area with a temperature rise of 10o C. The maximum allowable heat value inside the cabinet is 6 W x 2 x 10 = 120 W. Therefore, the heat generated inside the cabinet must be kept less than 120 W. If the heat generated is 120 W or more in the cabinet, some other cooling devices, such as cooling fins, must be incorporated in the unit. Example 2 (without a cooling fan): A cabinet has a 2 m2 radiation area with a temperature rise of 10o C. The maximum allowable heat value inside the cabinet is 4 W x 2 x 10 = 80 W. Therefore, the heat generated inside the cabinet must be kept less than 80 W. If the heat generated is 80 W or more in the cabinet, some other cooling devices, such as fan, or cooling fins, must be incorporated in the unit.

4.3 Emergency-Stop Circuit The electronic circuit in the controller requires about 100 milli-seconds to reach stable state when power is turned on. During this unstable period, the servo motor should not be turned on. To accomplish this purpose, HUST internal PLC has a "Servo-on Timer" with 1.5 seconds. When the timer is up, the controller sends an O-bit high (1) to turn on the servo driver. Fig 4-16 is an emergency stop circuit. When the hardware OT limit switch is touched or the E-stop button pushed, the controller will be in a state of emergency stop and the servo-on switch on the servo motor will trip off. For safety reason, the E-stop button, the hardware OT limit switch, and the E-stop relay should be connected in-series and the servo-release button in-parallel with the hardware OT limit switch. Please note that the E-stop button and the hardware OT limit switch are of normal-closed type. During normal operating condition, the servo-release button is at OFF position. After emergency stop has occurred and all power to servo motor has been cut off, servo-release button can be pushed in to supply power to servo motor to bring the machine tool to normal operating range.

Notes: 1. Relays A and B are protection circuit during power-on. The purpose is to prevent the

tool from being damaged in case of power-on failure that results in a total output. 2. Relay C is a servo-on relay. 3. Relay A and B are outputs in PLC. 4. Generally, Relay C has multiple connecting points for multiple servo. Each servo

motor requires independent connecting point. Do NOT connect servo motors in parallel because some servo motors cannot be connected in parallel. See Fig 4-17.

5.2.1 C-Bit explanation

Machine Lock/FEED-HOLD (C000) C000 = 1 (high), All machine tool operation stops. C000 = 0 (low), Machine tool operation in process. If bit C000 is set high (1), control unit will stop all CNC operations. It will remain stopped until C000 becomes low again. The relationship between C000 and the machine motion is shown as below.

Fig 6-2 Relationship between C000 Signal and Machine

Effect of FEED-HOLD on output control command G11 The Command Format: G11 Pxxx Lyyy 1. If yyy= 0 or void, this command is to turn ON the output specified by xxx which

can be turned OFF either by RESET or by G11 P-xxx. FEED-HOLD will not change the status of output xxx

2. If yyy= any number, this is to turn ON output xxx which can be turned OFF by

Feed-Hold. It will remain OFF as long as Feed-Hold is on. When Feed-Hold is released, output xxx will be back ON. Use RESET or G11 P-xxx to turn output xxx OFF.

Please refer to HUST H6C Operation Manual for more information on G11.

Fig 6-3

RESET (C001) C001 = 1 (high), RESET the whole system to initial status. C001 = 0 (low), RESET function is cleared.

Emergency Stop (C002) C002 = 1 (high), Controller reset and machine stops immediately. C002 = 0 (low), No action. Bit C002 informs the control unit to execute emergency stop. When bit C002 is set high (1), the control unit is reset and emergency stop is applied to the machine. Emergency stop signal turns off the servo ready signal. Refer to Section 5.4 for suggested circuit connection. When the problem that activated an emergency stop has been resolved, please reset the control unit and execute HOME process before normal operation.

Cycle Start (C004) C004 = 1 (high), Start program execution. (one pulse) C004 = 0 (low), No response. Bit C004 informs the control unit to start program execution. However, Cycle-Start signal (C004) is ignored when: 1. The control unit is already in "IN PROCESS" mode. 2. The control unit is not at AUTO, SINGLE, MDI, or TAPE mode. 3. Emergency stop signal (C002) is at high (1) 4. The control unit is in alarm state. (C007=1)

Program Restart-1 (C011)

C011 = 1 (high), Program Restart mode ON. If the program execution is interrupted for any reasons, the Restart function (C011=1 ) allows you to resume the execution from the program block where the program was interrupted. HUST H6C does not provide this function key on the keyboard and it must be processed through PLC. Follow the steps below to restart the interrupted program: 1. Press RESET. Use MPG to move tool away. If the interruption was caused by Em-

stop or servo alarm (Error 2), execute HOME, then RESET. 2. Press user installed [Restart] key to set C011 = 1 in PLC as follow. 3. In AUTO mode, press CYCST key to restart. At the end of M02 or M30, the restart

function will be automatically cleared.

Note that the M, T, S-code in the previously executed program blocks prior to program interruption will be re-executed during restart operation. Example: (See Fig 6-5) Assuming that the program was interrupted at block N40. When restart function is activated, the controller will calculate the coordinate change from N10 to N30, then move the tool to the end of N30 and continue the program execution from there.

Fig 5-5 Program restart When RE-START key is pressed (See Fig 6-5}, then [AUTO] and [CYCST], the CNC controller will calculate the executed distance from N10 to N30 and the cutting tool will then move to that point, from where the program execution will be continued.

Program Restart 2 (C012~C013) The command Bits C012~C013 are also used to restart the program from where the execution was interrupted. They are applied to the case when you interrupt the execution of the 1st program and jump to the 2nd program. Once you finish the 2nd program, you can use C012~C013 to go back to the 1st program and restart from where it was left. The procedures are as follows: 1. When program #1 is interrupted, activate C012=1 to store the interrupted block

number. 2. Jump to the 2nd program or do some other task such as JOG function. 3. Once finished the 2nd program, use PRNO Or PLC to return to program #1. 4. Set C013=1 to read the stored block number in step 1. 5. Set C011=1 (Restart-1). 6. Press CYCST.

Dry-run (C015) C015 = 1 (high), Dry-run mode selected. When C015=1, the control unit will execute dry run function. The dry run mode can be set at any time during program execution. When dry run is set, the feed-rate will change to fast speed at the beginning of next block. When dry run mode is turned OFF (C015=0), the feed-rate will return to normal cutting speed at the beginning of next block. Fig 5-6 shows the relationship between dry run mode and normal execution mode.

Fig 5-6 Time-relationship between dry run and normal execution mode

When the program restarts, it will directly execute the contents below the restart single block, C017 When C0171 (high) and the program restarts, it will not execute the single blocks before the restart sigle block and the function of direct execution of the contents below the restart single block is established. If the program is interrupted in execution due to whatever reasons, and when C017 = 1, the program will restart (with process of Co11 Bit) and execute from the place where it is interrupted. Program example: N10 S200 N20 G0 X50. Y100.

As shown in the above figure, start the RE-START function, and then execute AUTO, CYCST, the program will proceed from the original single block position.

Cursor Up And Cursor Down (C020~C021) C020 = 0 ~ 1 (Rising edge), the cursor moves up one line. C021 = 0 ~ 1 (Rising edge), the cursor moves down one line. Bit C020 informs the control unit to move the cursor one line up. It is effective only at the moment when the signal (C020) rises from low (0) to high (1). This function can be controlled by external input to remotely move the cursor. Bit C021 is for Cursor Down function.

Page Up And Page Down Key (C022~C023) C022 = 0 ~ 1 (Rising edge), move cursor one page up C023 = 0 ~ 1 (Rising edge), move cursor one page down When bit C022 is rising from low (0) to high (1), move cursor one page up. This function can be controlled from external input. Bit C023 is for Page-down function.

Bit searching function in Edit mode (First bit only) (C024) C024=1 (1 PULSE) In Edit mode and C24=1, it will search the first bit single block that was input in the input area.

When you key in X in the input area and C024=1, the cursor will point to the second block X50.Y50. When you key in M in the input area and C024=1, the cursor will jump and point to the fifth single block M30.

The program reading function is established with use of V10932 and V13449 (C025) V13449: Designates the program number for this function. V10932: Designates the program single block number for this function (the minimum single block number is 1). Before C025 is triggered ON with PLC, the values of V13449 and V10932 shall first be designated. When the function C025 is successfully executed, the relevant program contents that are read will be stored in the following variables: #13400 ----The system sends the message whether the letters A~Z in the

single block are used. BIT1 A 0= not use 1= use BIT26 Z #13401#13426 ----The system sends the contents of the letters A~Z. #13448 ----The system sends the message whether the letters A~Z in the

single block use #. BIT1 A 0= not use 1= use BIT26 Z Example: G01 A100 B#100 C#-100 Then, 13400=0x0000 000E (1110B) 13401=100 13402=100 13403=-100 13448=0x0000 000C (1100B) Note: R126 BIT27=0 When the function C025 is in execution, it reports Error when the

designated single block number is incorrect. (ERROR18.M). BIT27=1 When the function C025 is in execution, it does not report Error when the designated single block number is incorrect.

Option Stop (C026) C026 = 1 (high), Option Stop is enabled.

C026 = 0 (low), Option Stop is disabled. If C026 is set low (0), M01 block will be ignored during program execution. If C026 is set high (1), M01 block will stop program execution until CYCST is pressed again.

Option Skip (C027) C027 = 1 (high), Option Skip function is ON. C027 = 0 (low), Option Skip function is OFF. If C027 is set to 1, the block labeled with "/1" will be skipped during program execution. If C027 = 0, the block labeled with "/1" will be executed.

Speed Deceleration Selection for G31 Skip Function (C028) Bit C028 informs the control unit how to decelerate the servo motor when G31 skip function is encountered in the program. C028 is used in conjunction with the value in R190. Please refer to Operation Manual section 3.13 for G31 function C028 = 0 (low), servo motor ignores the value in R190 and decelerates linearly to zero. C028 = 1 (high) & R190 = 0, servo motor speed jumps to zero. C028 = 1 (high) & R190 0, servo motor will stop in a distance = value in R190.

PLC Ladder Simulation (C031) C031 = 1 (high), CNC is ready to accept ladder simulation procedures. C031 = 0 (low), ladder simulation stops. When C031 = 1, a RAM memory in HUST H6C controller will become available for user to test his ladder program that was edited in the personal computer. Note that the user's ladder program should have a line of C031=1 for the simulation to be effective. Please refer to Chapter 9 of HUST H6C Operation Manual for ladder simulation procedures.

M-, T-, S-code Command Finish Signal (C032~C034) C032 = 1 (high), M-code command is finished. C033 = 1 (high), T-code command is finished. C034 = 1 (high), S-code command is finished. When you use an M-code to do work on an external device, it normally takes some times for the external device to finish the work. When the work is finished, let C032=1 in your PLC. The H6C controller must receive this finish code for it to continue executing the next block. T-code and S-code work the same way. The M-code finish signals are effective for the range of M003~M499.

Round Corner Non-stop Operation (C036) C036 = 1 (high), Round Corner Non-stop Operation Between Blocks ON. When the tool motion changes from one direction (block) to another, it will produce a sharp corner and the motors will decelerate and accelerate at the intersection. This condition will produce an undesirable effect for some industrial machinery such as glue machine, flame or laser cutting machine. To overcome this problem, set C036=1 to produce a round corner and the motors will also run continuously when cornering with a cutting speed specified by the programmed federate (F). Note: C036 in NOT fot G00.
