SINAMICS G130/G150
474 List Manual (LH2), 07/2016, A5E03263479A
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).
When a sine-wave filter is connected, the short-circuit and the ground fault test are deactivated, as the filter could be
excited by the test pulse.
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), 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
