Parameter list
7.2 Parameter list
Parameter Function
P2164[0...2] Hysteresis frequency
deviation [Hz]
Hysteresis frequency for detecting permitted deviation (from setpoint) or frequency or speed. This
frequency controls bit 8 in status word 1 (r0052).
P2166[0...2] Delay time ramp up
completed [ms]
Delay time for signal that indicates completion of ramp-up.
P2167[0...2] Switch-off frequency
f_off [Hz]
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).
•
P2168[0...2] Delay time T_off [ms]
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.
P2170[0...2] Threshold current
I_thresh [%]
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]
Defines delay time prior to activation of current comparison.
P2172[0...2] Threshold DC-link
voltage [V]
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
voltage [ms]
Defines delay time prior to activation of threshold comparison.
P2177[0...2] Delay time for motor is
blocked [ms]
Delay time for identifying that the motor is blocked.
P2179 Current limit for no load
identified [%]
Threshold current for A922 (load missing) 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 (load missing) or a phase could be missing.
P2180 Delay time for load
missing [ms]
Delay time for identifying that the load is missing.
