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

- 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.

Motor data identification induction motor

The data is identified in the gamma equivalent circuit diagram and displayed in r19xx. The
motor parameters p0350, p0354, p0356, p0358 and p0360 taken from the motor data
identification refer to the T equivalent circuit diagram of the induction machine and cannot be
directly compared. This is the reason that an r parameter is listed in the table, which displays
the parameterized motor parameters in the gamma equivalent circuit diagram.
