Polarity Detection (Fn080)
The polarity detection function is used to detect the polarity and save the servomotor phase data in the SER-
VOPACK. After executing this function once, polarity detection is not necessary every time the power is
turned ON, so an immediate start of operation is possible.
(1) Checking Before Operation
Confirm the following before executing the polarity detection.
• Write Prohibited Setting (Fn010) is set to permit writing.
• Servo OFF state
• Servo Ready state
