74 Remote Command Set
MC
Description Motor check command
Syntax MC
Remarks This command scans for motors connected to the controller, and sets the motor type
based on its findings. If the piezo motor is found to be type ‘Tiny’ then velocity (VA)
setting is automatically reduced to 1750 if previously set above 1750. To accomplish this
task, the controller commands each axis to make a one-step move in the negative
direction followed by a similar step in the positive direction. This process is repeated for
all the four axes starting with the first one. If this command is issued when an axis is
moving, the controller will generate “MOTION IN PROGRESS” error message.
NOTE: Motor type and velocity changes are not automatically saved to non-volatile
memory. Issue the Save (SM) command after motor check to save all changes.
NOTE: Here is a command sequence which disables auto-motor type detection and
sets motor 1 (for example) to type ‘Standard’: 1ZZ1;1QM3;1SM
Example MC (Check all motors to determine type)
SM (Save new settings to memory)
