Siemens 125-3208 operating instructions Motor Data Identification

Startup Procedures

Motor Data Identification Continued

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 control.
