PNU Description
P095 Pick-up time for a contactor in the motor circuit
If the output (terminals U2, V2, W2) is switched through to the motor via a
contactor, and if this contactor is controlled by the relay output terminals
109 and 110, then the gating pulses may not be enabled until the contactor
has safely picked up. For this purpose, it may be necessary to
parameterize an additional delay time for the pick-up operation. The timer
set in P095 commences during a pick-up operation when the converter
reaches operating state o4. If the timer has still not run down by the time
the converter exits state o4, then the converter dwells in state o3.2 until the
timer has finished.
During the time period set in P095, the "Main contactor checkback" signal
must also switch to "1" if this function is activated (see P691). Otherwise
the converter dwells in state o3.3 until the timer has finished and fault
message F004 is then output with fault value 6.
P096 Run-on time for the converter fan
After the drive has stopped (an operating state ≥ 7.0 is reached), the fan
continues to run until the power section has cooled down.
This parameter can be used to set the minimum run-on time.
