CO: Act. filtered frequency 3

P-Group: ALARMS
Filtered frequency for monitoring behind first-order lowpass filter.
- |f_act| > f_1 (see P2155)
- |f_act| > f_2 (see P2157)
- |f_act| > f_3 (see P2159)
P2170[3]

Threshold current I_thresh

CStat: CUT
P-Group: ALARMS
Defines threshold current in [%] relative to P0305 (rated motor current) to be used in comparisons of I_act
and I_Thresh as illustrated in the diagram below.
|I_act| > I_thresh
I_act
Index:
P2170[0] : 1st. Drive data set (DDS)
P2170[1] : 2nd. Drive data set (DDS)
P2170[2] : 3rd. Drive data set (DDS)
Note:
This threshold controls bit 3 in status word 3 (r0053).
P2171[3]

Delay time current

CStat: CUT
P-Group: ALARMS
Defines delay time prior to activation of current comparison.
Index:
P2171[0] : 1st. Drive data set (DDS)
P2171[1] : 2nd. Drive data set (DDS)
P2171[2] : 3rd. Drive data set (DDS)
Details:
