(1) Preparation
The following conditions must be met to set the origin.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
• The servo ON signal (/S-ON) must be OFF.
(2) Operating Procedure
Use the following procedure.
• After execution of origin setting, the servo ready (/S-RDY) signal will become inactive
because the system position data will have been changed. Always turn the power
supply OFF and then ON again after execution of origin setting.
• After execution of origin setting, the servomotor phase data in the SERVOPACK will
be discarded. Execute polarity detection (Fn080) again to save the servomotor phase
data in the SERVOPACK.
