Description: Sets the configuration for the test pulse evaluation.
Bit 00: Check for conductor-to-conductor short circuit once/always when the pulses are enabled.
Bit 01: Check for ground fault once/always when the pulses are enabled.
Bit 02: Activation of the tests selected using bit 00 and/or bit 01 each time the pulses are enabled
Recommendation: If the ground fault test is incorrectly initiated because the motor is not at a complete standstill, then the pulse
cancellation delay time (p1228) should be increased.
Dependency: The ground fault test is only possible when the motor is stationary, and is therefore only realized when flying restart is
deactivated (p1200 = 0).
Refer to: p0287
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.
For chassis power units, the ground fault is also determined using the summed output current (see p0287).
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
