Parameters to control the motor data identification
The following parameters influence the motor data identification:
Table 4- 11 Parameters for control
Static measurement (motor data identification)
Rotating measurement
• 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 per-
mitted
1)
• p0640 current limit
• p1082 maximum speed
• p1958 motor data identification ramp-
up/ramp-down time
• p1959 rotating measurement configuration
• p1960 rotating measurement selection
1)
The setting of p1959 has the following effects for the direction of rotation 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
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 reco
mmend 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.
