Issue Details

I am trying to configure the break for my motor drive device but in the SoftMotion axis configuration menu the brake option is greyed out. My motor drive is connected to a C series motor drive interface module and I know my motor drive supports the break functionality so why am I observing this behaviour?

Solution

For SoftMotion to be able to properly communicate with your motor drive and set the brake mechanism you will need to use an EtherCAT enabled drive device.

Additional Information

This issue is usually caused when you connect a C series motor drive interface module to an analogue motor drive. As the interface module has no way of communicating with the firmware on the motor drive it will by default disable the break configuration option.
