SINAMICS G120P controlled from SIMATIC S7-1200

unknown user

I'm new in Siemens drives domain and i have few question:
The main things that i want to do are :
1. Turn ON/OFF the Motor.
2. Control the speed of my Motor.
3. Know the actual speed (if it's possible).
And all that via my PLC (S7-1200) connected to my desktop computer.

So my question is, how can i do that ? and do i need only a profinet connection or do i have to add physical connection between my PLC and the Drive.

You can use a communication or direct IO wiring:

As far as I know, Siemens does not offer a CAN module for the S7-1200 so there are this two solutions:

• CU230P-2 DP => PROFIBUS:
  The biggest problem is the CU230P-2 DP has PROFIBUS, but the S7-1200 by default not, you have to add a communication module CM 1243-5 (PROFIBUS Master, 6GK7243-5DX30-0XE0) to the S7-1200. and a PROFIBUS cable. Yu can use the SINA_SPEED block inside the S7-1200 to control the motor. 'There is a example with PROFINET:

• CU230P-2 and CU230P-2 CAN (can de done with CU230P -2 DP too)
  Here you have to use digital IO and a analogue signal (0-10V)  (I didn't check it, but I expect the CU230P has a analogue input.) for the setpoint.
