6. Press
to advance to setting
P1910=3. Press
to confirm and
save the setting.
When P1910=3, Alarm 0541 (motor
data identification active) is output
and internally P0340 is set to 2.
Initiate the measuring operation with
a continuous (steady-state) ON
command.
On completion of the motor data
identification routine, P1910 resets
(P1910=0, motor data identification
routine inhibited) and Alarm A0541 is
cleared (deleted).
7. To set the SED2 into a defined state,
issue an OFF1 command.
NOTES:
1. Motor must be cool to perform motor data identification.
2. Before selecting motor data identification, perform quick commissioning.
3. This measurement may take several minutes depending on motor size.
4. When P1910=1, the calculated value for stator resistance (P0350) is overwritten.
5. When P1910=2, the values already calculated (P0350) are not overwritten.
6. When choosing the setting for measurement, observe the following:
- P1910=1 means that the value is actually adopted as P0350 parameter setting and applied to the
control as well as being shown in the read-only parameters.
- P1910=2 means that the value is only displayed. That is, it is shown for checking purposes in the read-
only parameter r1912 (identified stator resistance). The value is not applied to the controller.
