thx for your help.
You are right , you can set the inputs true every where, but it would be easier if you could just enable mc_power and the motor works
Maybe sombodey knows if you can set the inputs true in the i/o mapping of the EL 7031.
The el7031 is not (yet) supported by codesys . I think that is a pitty because it is one of the cheapest way to connect a steppermotor to ethercat / codesys and play with it .
I think stepping into softmotion would be a lot more fun for a lot of people if this would be a plug and play drive for the nema 17 stepper motor range .
