MO (Motor Off)
[Setting]
DESCRIPTION:
The MO command shuts off the PID control algorithm and the servo enable signal. The controller will
continue to monitor the motor position. To turn the motor back on use the
SH (Servo Here) command.
The servo cannot be turned off (MO) while it is commanded to move. Issuing the MO command in this
mode will cause a command error. Use the
ST (Stop) , AM (After Motion) or AB (Abort) commands
before MO.
ARGUMENTS: MO XYZW or ABCD
USAGE:
