MICROMASTER 440 Parameter List
214 6SE6400-5BB00-0BP0
P2166[3] Delay time ramp up completed Min: 0
CStat: CUT Datatype: U16 Unit: ms Def: 10
P-Group: ALARMS Active: Immediately QuickComm.: No Max: 10000
Delay time for signal that indicates completion of ramp-up.
Index:
P2166[0] : 1st. Drive data set (DDS)
P2166[1] : 2nd. Drive data set (DDS)
P2166[2] : 3rd. Drive data set (DDS)
Details:
See diagram in P2174.
P2167[3] Switch-off frequency f_off Min: 0.00
CStat: CUT Datatype: Float Unit: Hz Def: 1.00
P-Group: ALARMS Active: Immediately QuickComm.: No Max: 10.00
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).
Restriction:
- The monitoring function |f_act| <= P2167 (f_off) is not updated and pulses are not disabled, if motor
holding brake (MHB, P1215 = 1) is enabled.

occurs.
