(2) Magnetic pole detection
For magnetic pole detection methods, refer to the Servo Amplifier Instruction Manual for your servo
amplifier.
When an incremental scale is used, magnetic pole detection is performed at every power on. The magnetic
pole detection is started when the first servo-on command following power on is received. Completion of
the magnetic pole detection turns the servo on.
