PLC control Nema 23 external linear actuator stepper motor system 

I have a servo motor that uses pulses but it says +-20v max

@@osamakhalaf6789 So, you need resistors to solve this problem.

Do you mean in PUL + or PUL- ?

1. According to the "Pulse/rev Table" of the drive, set the number of pulses that the motor needs to receive for each revolution. This can alleviate the jitter of the motor. 2. The speed can be adjusted according to the output pulse frequency. 1:31 in the video, D100 stores the output frequency parameter, the larger the value, the higher the speed. 3. Please read carefully the use method of pulse output instruction in your PLC programming manual. 4. We are using Omron CP1E N40DT-D, each company's PLC has its own programming method, please note.

Your PLC may use a potentiometer if it has an analog module, depending on the speed of the pulses.

Yes, you can control the number of pulses sent by the PLC to control the angle of rotation of the stepper motor. such as, 1. When the step angle of the stepper motor is 1.8°, it means that the motor needs 200 pulses per revolution (360/1.8=200) 2. When the stepper drive's subdivision parameter (Pulse/rev) is 3600, the step angle = 360/3600 = 0.1°, which means that the motor rotates 0.1° after each pulse is received. If we want to rotate 100°, then only 1000 pulses are needed.

Thank you sir

Add SPED instruction, modify the control data to reverse to achieve.

My PLC is CP1E-N40DT-D(Transistor output type) . In my memory, the N40DR-D is relay output type PLC, so it cannot send pulses to the stepper motor. So I think it can't control the stepper motor. You'd better check out the OMRON PLC hardware manual.

Common interlock commands cannot drive stepper motors, which are controlled by pulse commands (command to stepper drive). In addition, no contactor can be added between the stepper drive and the PLC.

1. You need to know how many pulses your motor needs for one revolution. 2. You need to know how far your screw rod moves in one revolution (lead = pitch * number of lines)

In the video 1:29 , or this video 4:40, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TLJl0p0X9k4.html

CP1E N40DT-D

Refer to Omron PLC hardware and software manuals, these ports are pulse fixed output ports.

@@ATOcom thank you sir~~

Transistor output.

@@ATOcom Has it been available of pulse command or do you just on/off the output pin so that the ouput pin act like pulse output?

@@braineedly7543 Yes, the pulse command is used.

​@@ATOcom sir if we have PLC that is not compatible of pulse output, can we make pulse output by ON/OFF the output pin quickly?

@@braineedly7543 In principle, the pulse is only high level and low level. As long as you can control the width of the high level and low level, pulse generation can be realized, but all of this is not practical. It is recommended that you replace the PLC.

Add a reverse button (external input) to activate the reverse command. The control logic is the same as the forward rotation, except that the reverse code is different from the forward direction. You can refer to the instructions of the PLC. Place the instruction position before the interrupt instruction.

Ouhh..should I add the interlock system to the forward and reversed ladder diagram ... if necessary, can you tell me the short code to make the interlock... I'm still new

@@azimfitri7346 No need to add an interlocking system.

sir, if I want to add a pilot lamp to show foward is running, where should I place between internal data storage, pulse transmit, starting output pulse or pulse interrupt program

@@azimfitri7346 The program is scanned from top to bottom, so you put it in front of the interrupt program and it's OK.

Do I had add holding contact in ladder to run while I release push button??.if do can you give me address to add holding contact Thank you

I see you did not add holding contact but I have followed ... but not become

@@azimfitri7346 Whether the PLC brand you use is different. In my PLC, only need to transfer the command data to the special storage area, it will continuously send out pulses. Maybe you look up your PLC user manual to find usage examples.

@@ATOcom the plc i use is plc omron cp1e-N20DT-D

@@ATOcom so what do i need to do to keep it going ... please tell me.. Thank you
