Polarity Sensor Setting

The polarity sensor detects the polarity of the Servomotor. You must set a parameter to specify

whether the Linear Servomotor that is connected to the SERVOPACK has a polarity sensor.

Specify whether there is a polarity sensor in Pn080 = n.X (Polarity Sensor Selection).

If the Linear Servomotor has a polarity sensor, set Pn080 to n.0 (Use polarity sensor)

(default setting).

If the Linear Servomotor does not have a polarity sensor, set Pn080 to n.1 (Do not use

polarity sensor). Turn the power supply OFF and ON again to enable the new setting.

(default setting)

If you set Pn080 to n.0 (Use polarity sensor) and the Linear Servomotor that is con-

nected to the SERVOPACK does not have a polarity sensor, an A.C21 alarm (Polarity Sensor

Error) will occur when you turn the power supply OFF and ON again.

Use polarity sensor.

Do not use polarity sensor.
