Homing
Dog type homing
Set the creep speed of homing in advance to prevent shock from hitting the machine. On detection of a zero pulse, CR
(homing) is turned from off to on. At the same time, the servo amplifier clears the droop pulses, comes to a sudden stop, and
stores the stop position into the non-volatile memory as the home position absolute position data.
CR should be turned on after checking that INP has turned on. If this condition is not satisfied, [AL. 096 Home position setting
warning] occurs. If homing is performed correctly, the alarm is automatically canceled.
