Host Command Reference
PN - Probe On Demand
Compatibility: Stepper drives
See also:
EF, MC commands
Perform a full-current probe of the motor. The motor’s maximum rated current is used as defined by the MC
command. This allows the drive to dynamically measure electrical parameters such as inductance and resistance,
which are used to optimize the drive’s control over the motor.
This probe is automatically done on power-up and after an EF command is issued, but may be performed at any
time using the PN command.
NOTE: This operation will briefly energize the motor with full current. Use caution when executing the PN
command as this may cause slight movement of the motor shaft.
