CONTROL SERVO MOTOR OVER ETHERCAT BY PLC APP

Hi,

Shall we control a servo motor directly by only using PLC app with "PLC Open" library without using Motion App?

If yes then could you tell me how to declare the Axis variable as attched picture?

Thank you!

When drives only are connected as an IO you cannot use the standard motion function blocks like MC_Power. These are interfaces to the motion runtime. You will have to handle the control and status word as well as the set frequency/speed by hand.
