I have Siemens Simatic S7-1200, Stepper Motor Nema 23 Planetary Geared (2,8A) -> https://www.omc-stepperonline.com/geared-stepper-motor/nema-23-stepper-motor-bipolar-l56mm-w-gear-raio-471-planetary-gearbox-23hs22-2804s-pg47.html 

My Question is:

Can I drive Stepper Motor directly with Simatic S7-1200? Otherwise:

What Stepper Motor Driver will be the best choise for controlling my Stepper Motor?

1. Is it possible to power and control the stepper motor directly from PLC S7-1200?

2. There are many of Stepper Motor Controler units on market. I'm not sure what is the best choise to use with S7-1200, thats why I'm asking here on forum. For Example, I found this stepper motor controller:

https://www.amazon.com/SainSmart-Micro-Stepping-Stepper-Driver-ST-M5045/dp/B00DFSF9GE/ref=pd_bxgy_60_3/147-8451807-3566906?_encoding=UTF8&pd_rd_i=B00DFSF9GE&pd_rd_r=0D1MZ7EQ2H0QMS5CT8YF&pd_rd_w=fOhV0&pd_rd_wg=NSWT7&psc=1&refRID=0D1MZ7EQ2H0QMS5CT8YF

This controller is powered by 24V, But I'm not sure if this is the best choise becouse control signals are 5V and I'm not sure if they are supposed to be used with PLC...

I also found this controller from Siemens : SIMATIC FM 353 Stepper Drive: Link:

https://cache.industry.siemens.com/dl/files/357/2106357/att_51481/v1/FM353_0808_b.pdf

But datasheet only tells that driver can be used with S7 300 , so I'm not sure if it can be used with S7 1200...

What would be the easyiest way of controlling my stepper motor?

Hello.

We have used similar parts than what you are linking to from Amazon, on S7-1200 systems.

Use the following as a guide only:

Thank You for this information! It really helps.

How can I know if my PLC has Yang or Yin outputs and what is the difference, where to use each of them?

Look at the picture .. think of the left side transistors as relays. From there it should be clear which PLC you have. The output is 24Vdc if you use the S7-1200. That is PNP or "YIN" from the picture.

Are you suggesting powering the stepper motor from a PLC output?

Or, are you suggesting simply that the control signals that tell the stepper to move come from a PLC output?

You need a Stepper Motor Driver / Controller between the PLC PTO output and the motor.  Google can help you find one that matches the motor requirements.
