Remarks
This command is used to manually set the motor type of an axis. Send the Motors Check (MC)
command to have the controller determine what motors (if any) are connected. Note that for
motor type ‘Tiny’, velocity should not exceed 1750 step/sec. To save the setting to non-volatile
memory, issue the Save (SM) command.
Note that the controller may change this setting if auto motor detection is enabled by setting bit

detection is enabled the controller checks motor presence and type automatically during all
