- ATO external stepper linear actuator in this video is 2 phase 4 wire comes in Nema 23 frame size. We will show you how to use PLC connect to the hybrid stepper motor system, and control this external stepper motor linear actuator for simple forward and reverse motion by the pulse and direction command issued by PLC.

Note:
PUL, DIR, ENA signals are 24V, please connect a 2kΩ resistor in series. (If it is 12V, please connect a 1kΩ resistor in series)
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- ?
Thank you so much for the video..i got a great idea for my project!!
That is some decent wiring brooooooo
Can i see full the ladder please?
Dear sir how does the servo drive read the g code coming from the program and gives according to it plus to servo motor
could you show the modification made in the program to do the reverse?
Add SPED instruction, modify the control data to reverse to achieve.
Hello, I made the same hardware configuration that the video has, but the motor trembles and goes slow, what data would I have to put in the pulse frequencies? And what data for the speed at which the video engine is running
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.
Very good. What about speed controll? Is it possible to connect a potentiometer through CP1LE for this system?
Your PLC may use a potentiometer if it has an analog module, depending on the speed of the pulses.
Hello sir, I have a question i want to ask that if i want to control the stepper motor to rotate at a specific angle CW and CCW. Is it possible to do that and how we determine the parameters in DRVA function? Thank you for your video.
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
I am a beginner in plc, i have cp1e-N40DR-D, I see it is look like yours (but not sure). Can my plc control step mortor?
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.
0.02 input diagram.you can write it down?
hello how can i calculate the distance wich the motor did during working
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)
Sir I'm beginner use plc if i make interlock push button on programming to active stepper motor...do i need to install contactor for addition..
Please explain to me
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.
Thank your for sharing sir. May I ask you about PLC model?
CP1E N40DT-D
Can i have wiring diagram sir
Hello sir what kind of output PLC you used?
Was that relay output or transistor output?
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.
could you please put a wiring diagram?

sorry sir, i 'm a begineer, and i would like to know how can define 100.00 for PUL-, .02 for DIR- , and .04for ENA- ? as i didnt see any output setting in plc program. thz much
Refer to Omron PLC hardware and software manuals, these ports are pulse fixed output ports.
@@ATOcom thank you sir~~
sorry sir, here you have an addition for reversed, so did you make it to the new space or did you add it to the control point foward..because you didn't show it on the ladder diagram again ... so I don't understand there..thanks sir
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.
Hi, i have a question what´s the configuration (out pulses) in the program of the PLC Omron?
Thanks
In the video 1:29 , or this video 4:40, th-cam.com/video/TLJl0p0X9k4/w-d-xo.html
sorry sir .. I've followed your ladder ... but my stepper motor only rotates when the switch is pressed ... while your video looks like there is a holding contact when the switch is released for the stepper motor to keep rotating
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
Sir Aap connection karke dikhaye please sir aap ek video plc ke upar banaye boley bol bol kar taar
Thank you for your advice, we will improve that.
ALL OK, UNTIL POWER DOWN, LOOSE ALL POINTS
