4-11-3 Servomotor Origin Search

H Servomotor Origin Search (Fn003)
• The Servomotor origin search function rotates the Servomotor to the encoder's origin pulse (phase Z)
position, and then stops the Servomotor.
• Use this function to adjust the origin position of the Servomotor shaft and mechanical system.
Note 1. Execute the Servomotor origin search before connecting the Servomotor shaft and mechani-
cal system.
Note 2. The RUN command input must be turned OFF. Also, if the RUN signal is set to be always ON
(Pn50A.1 = 7), either change the setting to "Always OFF" (setting value: 8) or change the set-
ting to another value, then turn OFF the power supply once, and then turn it ON again.
