4.13 Motor data identification
Parameters to control the motor data identification
The following parameters influence the motor data identification:

The setting of p1959 has the following effects for the direction of rotation p1821:
1)
- Positive direction permitted, with setting p1821=0 means: Clockwise direction of rotation
- Negative direction permitted, with setting p1821=1 means: Counter-clockwise direction of rotation
Note
If a brake is being used and is operational (p1215 = 1, 3), the stationary measurement is
made with closed brake. If possible (e.g. no hanging/suspended axis), we recommend that
the brake is opened before the motor data identification (p1215 = 2). This also means that
the encoder size can be adjusted and the commutation angle calibrated.
