Since the type plate data contains the initialization values for identification, you must ensure
that it is entered correctly and consistently to enable the above data to be determined.
Parameters to control the MotID
The following parameters influence the MotID:

Static measurement (motor data identification)
p0640 current limit
•
p1215 Motor holding brake configuration
•
p1909 Motor data identification control word
•
p1910 Motor data identification, stationary
•
p1959.14/.15 clockwise/counter-clockwise direction or
•
rotation permitted
Note:
If a brake is being used and is operational (p1215 = 1, 3), then the stationary measurement with closed brake is carried-
out. If possible (e.g. no hanging/suspended axis), we recommend that the brake is opened before the MotID (p1215 = 2).
This also means that the encoder size can be adjusted and the angular commutation calibrated.

Motor data identification - induction motor

Induction motor
The data are identified in the gamma equivalent circuit diagram and displayed in r19xx. The
motor parameters p0350, p0354, p0356, p0358 and p0360 taken from the MotID 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.
