7.2 Parameter list
p1901
Test pulse evaluation configuration / Test puls config
G120X_DP (PM330),
Access level: 3
G120X_PN (PM330),
Can be changed: T
G120X_USS (PM330)
Unit group: -
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).
See also: 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).

established during the test pulses.
