Note:
If a conductor-to-conductor short-circuit is detected during the test, this is displayed in r1902.1.
If a ground fault is detected during the test, this is displayed in r1902.2.
For bit 02 = 0:
If the test was successful once after POWER ON (see r1902.0), then it is not repeated.
For bit 02 = 1:
The test is not only performed after POWER ON, but also each time the pulses are enabled.
Description:
Displays the status of the test pulse evaluation.
Note:
If the ground fault test was selected, but not successfully performed, then sufficient current was not be able to be
established during the test pulses.
For bit 04:
A test pulse longer than one sampling time has occurred
Description:
Sets the configuration for the motor data identification.
