2.2 List of parameters
p1901 Test pulse evaluation configuration / Test puls config
VECTOR_G Can be changed: T
Data type: Unsigned32
P-Group: Motor identification
Not for motor type: -
Min
-
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.
Bit field: Bit
00
01
02
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.
r1902 Test pulse evaluation status / Test puls ev stat
VECTOR_G Can be changed: -
Data type: Unsigned32

Description: Displays the status of the test pulse evaluation.
Bit field: Bit

04
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
