Determine number of pole pairs

If the number of pole pairs of the motor is not specified in the data sheet, you can determine it experimentally.

Procedure

Prerequisite: the motor has been configured in accordance with the chapter Quick start guide.

1. Ensure that the parameter 0x2003:13 "Motor pole pairs" has the value 1.

2. Send the request to the motor to perform a full rotation.

The motor only performs a partial rotation because the number of pole pairs has not yet been set correctly.

3. Repeat the request until the motor has completed one full rotation.

The number of requests needed for a full rotation corresponds to the number of pole pairs.

4. Enter the number of pole pairs in the parameter 0x2003:13 "Motor pole pairs".

5. Perform the scanning of the motor again: Scan motor
