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 Servo Here command (SH). This
command is not allowed while the servo is commanded in motion. Use the ST command first in that case.
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, AM or AB commands before MO.
The action of performing MO then SH will clear any non critical amplifier alarms.
ARGUMENTS: MO XYZW or ABCDEFGH
USAGE:
OPERAND USAGE:
_MOn will return the state of the motor where n is an axis letter, 0 = servo loop on and 1 = servo loop off.
RELATED COMMANDS:
EXAMPLES:
NOTE: The MO command is useful for positioning the motors by hand. Turn them back on with the SH command.

"SH" Servo Here
“AB” Abort

Bob=_MO Sets Bob equal to the servo status
Bob= Return value of Bob. If 1, in motor off mode,
If 0, in servo mode
