9.2 Procedure

CAUTION

It is essential that the following checks are carried out before the pulse and controller enables are activated:

Make sure that the encoder parameters have been assigned correctly, particularly if the speed actual value needs to be inverted.

Rotate the motor manually to check that the speed actual value has the correct sign and that the position actual value is incremented or decremented accordingly.

Please note that parameters also have to be assigned for the speed actual value inversion on the NCK side (axis-specific machine data, MD 32110 – ENC_FEEDBACK_POL[0] = –1).

When initially testing the motion-based process of rotor position identification, you should reduce the current for safety reasons to 10%, for example (MD 1105 = 10%). The current reduction does not have any effect on the process; it only becomes active once identification is complete.
