7
8) on reaching standstill, or whether it remains active until leaving the function.
Pn.58: Quick stop mode
Bit Meaning Value Explanation
3 Status bit at standstill
0: Status bit on
The status bit "abnormal stopping" remains active until
leaving the function
8: Status bit off
The status bit "abnormal stopping" is reset when the drive
has reached standstill
7.13.5.1 Quick stop in the V/F characteristic operation
For abnormal stopping with v/f-characteristic control, the drive is decelerated with the adjusted ramp time, and
with the differential controller, respectively.
Pn.58: Quick stop mode
Bit Meaning Value Explanation
0
Quick stop mode
(V/F-characteristic
operation)
0: Ramp generator The deceleration time is Pn.60
1: Differential con-
troller
The deceleration time is dependent on the difference
current limit (Pn.59) - actual current. The time constant
of the controller is adjusted by Pn.60, the setpoint is
adjusted by Pn.59.
1
Quick stop act. value
(V/F-characteristic
operation)
0: Apparent current
Current limit for deceleration refers to the apparent
current
2: Active current
Current limit for deceleration refers to the active cur-
rent
The ramp time of the abnormal stopping function or the time constant of the controller are set in Pn.60 depen-
ding on the adjustment of Pn.58.
Pn.60: Quick stop deceleration time
Value Explanation
0..300 s Ramp time and time constant of the controller, respectively
The current limit for the differential control is set in Pn.59 "abnormal stopping level".
Pn.59: Quick stop level
Value Explanation
0...200 % Current limit for difference control = 0...200% rated inverter current (In.01)
