•	p0353 motor series inductance		•	p0323 maximum motor current
•	p0400ff encoder data		•	p0353 motor series inductance
			•	p0400ff encoder data

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:

Table 3-10 Parameters for control

Static measurement (motor data identification)				rotating measurement
• p0640 current limit		•	p0640 current limit
• p1215	Motor holding brake configuration	•	p1082	Maximum speed
• p1909	Motor data identification control word	• p1958 motor data identification ramp-up/ramp-down time
• p1910	Motor data identification, stationary	•	p1959	Rotating measurement configuration
• p1959.14/.15 clockwise/counter-clockwise direction or		•	p1960	Rotating measurement selection
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.

3.12.1Motor 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.
