P2167[0...2]
Switch-off frequency f_off
[Hz]
0.00 - 10.00 1.00 U, T - DDS Float 3
Defines the threshold of the monitoring function |f_act| > P2167 (f_off). P2167 influences following func-
tions:
• If the actual frequency falls below this threshold and the time delay has expired, bit 1 in status word 2
(r0053) is reset.
• If an OFF1 or OFF3 was applied and bit 1 is reset the converter will disable the pulse (OFF2).
P2168[0...2]
Delay time T_off [ms]

DDS
U16
3
Defines time for which the converter may operate below switch-off frequency (P2167) before switch off
occurs.
Dependency:
Active if holding brake (P1215) not parameterized.
P2170[0...2]
Threshold current I_thresh
[%]
0.00 - 400.0 100.0 U, T - DDS Float 3
Defines threshold current relative to P0305 (rated motor current) to be used in comparisons of I_act and
I_Thresh. This threshold controls bit 3 in status word 3 (r0053).
P2171[0...2]
Delay time current [ms]

3
Defines delay time prior to activation of current comparison.
P2172[0...2]
Threshold DC-link voltage
[V]
0 - 2000 800 U, T - DDS U16 3
Defines DC link voltage to be compared to actual voltage. This voltage controls bits 7 and 8 in status word
3 (r0053).
P2173[0...2]
Delay time DC-link volt-
age [ms]
0 - 10000 10 U, T - DDS U16 3
Defines delay time prior to activation of threshold comparison.
P2177[0...2]
Delay time for motor is
blocked [ms]
0 - 10000 10 U, T - DDS U16 3
Delay time for identifying that the motor is blocked.
P2179
Current limit for no load
identified [%]
0.00 - 10.0 3.0 U, T - - Float 3
Threshold current for A922 (no load applied to converter) relative to P0305 (rated motor current).
Notice:
If a motor setpoint cannot be entered and the current limit (P2179) is not exceeded, warning A922 (no
load applied) is issued when delay time (P2180) expires.
Note:
It may be that the motor is not connected or a phase could be missing.
P2180
Delay time for no-load
detection [ms]
0 - 10000 2000 U, T - - U16 3
Delay time for detecting a missing output load.
