PL09: Magnetic pole detection level setting
Servo amplifiers that are compatible with this actuator detect the magnetic pole by applying DC
voltage to the motor power line during excitation of the actuator.
Precautions for using this method are described below.
◆
The magnetic pole cannot be detected under the following conditions:
(1) The actuator output shaft is locked from outside and cannot be moved
(2) The actuator output shaft is driven by an external force
◆
The magnetic pole may not be detected under the following conditions
(3) A force higher than the torque values listed below is applied inhibiting the actuator from rotating
during magnetic pole detection.
Actuator Model No.

If the servo amplifier outputs the AL27.1: Initial magnetic pole detection error even when neither
(1) or (2) condition is present, a force higher than the torque values listed above may be applied
inhibiting the rotation.
In this case, the magnetic pole may be detected by changing the servo amplifier configuration
parameter PL09: Magnetic pole detection voltage level.
However, if a force higher than the torque values listed below is applied inhibiting the rotation,
the magnetic pole cannot be detected. Reduce the force inhibiting the rotation.
Actuator Model No.
