SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Defines the threshold of the monitoring function |f_act| > P2167 (f_off).
P2167 influences following functions:
• If the actual frequency falls below this threshold and the time delay has expired, bit 1 in status word 2 (r0053) is
reset.
• If a OFF1 or OFF3 was applied and bit 1 is reset the inverter will disable the pulse (OFF2).
Description: Defines time for which the inverter may operate below switch-off frequency (P2167) before switch off occurs.
Dependency: Active if holding brake (P1215) not parameterized.
Note: See diagram in P2167 (switch-off frequency)
Description: Filtered speed (or frequency) for monitoring behind first-order lowpass filter.
