Preliminary remark

This chapter provides information on checking a direction of rotation and determining the commutation offset for third-party motors.

Please observe the following notes:

A commutation offset can only be determined and stored for motors with resolver, absolute encoder (single- or multi-turn) or the part-absolute MES.

For incremental encoders (sine/cosine or TTL signals) the “Wake&Shake” routine must be configured. This is necessary, since in this case the commutation offset is not constant. The "Wake&Shake" routine redetermines the commutation offset after each start.

Preliminary remark 1:

Do not use the electronic identification plate!

If a motor with an EnDat or BISS encoder is used, we recommend not using an electronic identification plate.

Notice

Inversion of the counting direction.

All direction settings must have their default values. Do not invert a counting direction before the correct commutation angle was determined!

A mechanical offset related to the rotor position, or an electrical offset related to the electrical rotation can be determined. Both procedures are explained below.

Preliminary remark 2:

Further information can be obtained in the parameters:
