Rating plate data
Input of the rating plate data requires the following parameters:
Table 3- 10 Rating plate data
Induction motor
p0304 rated voltage
•
p0305 rated current
•
p0307 rated power
•
p0308 rated power factor (cos ϕ)
•
p0310 rated frequency
•
p0311 rated speed
•
p0322 maximum motor speed
•
p0353 motor series inductance
•
p0400ff encoder data
•
Since the rating 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- 11 Parameters for control
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 Positive/negative direction 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.
*The p1959 setting has the following effects on the rotational direction parameter p1821:
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
