5.9.5 Origin Setting (Fn020)

The origin setting function is used to set the current position as the origin. After executing this function once,
origin setting is not necessary every time the power is turned ON, so an immediate start of operation is possi-
ble.
Follow the steps below to detect the polarity.
• After execution of origin setting, the servo ready (/S-RDY) signal will become inactive and the servo will be
unable to draw power since the system position data will have been changed. Always turn the power sup-
ply 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. Exe-
cute polarity detection (Fn080) again to save the servomotor phase data in the SERVOPACK.

The following settings are required before setting origin.
• If the S-ON input signal is ON, turn OFF the signal.
• If Pn50A.1 is set to 7 (i.e., the servo is always ON), change the value.
