Hello all,

I am quite new to Easy Motion Control and to Simatic in general. We have a customer where we are retrofitting an old analog drive with a Sinamics DCM. The application is a positionning drive.

Since we don't have Epos, or the DCC positioning capabilities for positioning with the DCM, i was thinking of using the Easy Motion Control for this customer, since they already have an S7-416 PLC with Step7(non TIA portal)

My questions are:

1- Is EasyMotionControl capable of interfacing with a Profidrive capable PLC over Profibus using the telegram 3? i mean the drive captures the encoder signal and sends it through profidrive to the PLC and receives the speed setpoint from the PLC via Profibus? I read some documentation but it was not too clear for me.

2- How to know if the Easy Motion Control runtime license is activated or not on the S7-400 in Step 7 V5.x and for how many axes? Also, is there any way to know what are the runtime licenses activated on a PLC in general

Thanks

Philippe

1. Check the On- and Output driver.
   I assume you will have to use the universal input driver and copy the encoder data.
   Try to use the output driver MM4_DP. If this doesn't work you have to use the universal output driver and copy the required data.
   
   
2. The license does not have to installed/activated.
