If using the SERVOPACK’s phase-C pulse output for a zero point return, rotate the servomotor twice or
more before starting a zero point return. If the configuration prevents the servomotor from rotating the ser-
vomotor or more, perform a zero point return at a motor speed of 600 min
-1 or below. If the motor speed is
faster than 600 min
-1
, the phase-C pulse output may not be output correctly.

Set the number of pulses for PG output signals (PAO, /PAO, PBO, /PBO) externally from the SERVOPACK.
Feedback pulses from the encoder per revolution are divided inside the SERVOPACK by the number set in Pn201 before
being output. (Set according to the system specifications of the machine or host controller.)
The setting range varies with the number of encoder pulses for the servomotor used.
