Motor Data Identification Continued
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 control.

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.
