Protective functions
Pn.60: Quick stop time
Value Explanation
0...300 s Deceleration ramp for abnormal stopping-function
At abnormal stopping with differential controller, this ramp is modied that the drive decelerates preferably at a
current limit.
This current limit is set in Pn.59 "abnormal stopping level".
Pn.59: Quick stop level
Value Explanation
0...200% Current limit for deceleration = 0..200% rated inverter current (In.01)
With Pn.58 bit 1 can be selected if the inverter shall decelerate at the active current limit or at the apparent
current limit.

Time monitoring abnormal stopping
For safety, a maximum time for the abnormal stopping-function can be programmed.
Pn.68: Max. abn. stopping time
Value Explanation
0,01...100,00 s
time after which the inverter switches from malfunction- ("abnormal stop" A.XX) to the error
state (E.XX)
If the inverter is still in the malfunction state (A.XX) after this time (no RESET or automatic restart was exe-
cuted), the inverter switches off the modulation and changes to the corresponding error state (A.XX => E.XX).
Abnormal stopping via control word
Abnormal stopping can also be triggered via the control word (SY.43 and SY.50, respectively ). The parameter
Pn.58 abnormal stopping mode determines the behaviour of the abnormal stopping via control word.
