SERVOPACK with Semi-closed Loop Control for Rotary Motors
After the function has been completed the motor power will turn OFF and the Servo Ready signal will turn
ON. Then the function cannot be executed even if the /P-DET signal is turned ON and OFF. Then the control
power is restored, the function must be executed again.
Utility Function: Pole Detection (Fn080)
This utility function is executed using Panel operator, Digital operator and SigmaWin+.
(3) Execution of the Function with MECHATROLINK and Network Option Model
Servo ON Command
Utility Function: Pole Detection (Fn080)
