!MS command does not work ?

Hello,

Which control mode are you operating in: Open loop or closed loop? If closed loop then which closed loop mode?

When in closed loop position relative mode, the !MS command acts by essentially sending a command relative to the current position of the motor when the !MS command is sent. This will stop the motor in that specific position however dependent on the tuning of your PID gains you may still observe motion on the motor shaft as the motor is trying to track to the command position.

!MS does not remove power to the motor, which I think is what you are expecting. Rather it holds the motor in the position the motor was in when the !MS command is sent. In order to remove power to the motor you would need to use Emergency Stop (!EX) however this cannot be done for each individual channel, when !EX is sent both motor channels are effected.

Thank you for your feedback. I will make sure to include a more detailed description in our User Manual Errata and we will expand the description in our next revision of the manual.
