Quick stop time
P
0 ... 320.00 s
[ 0.10 ]
Setting of the stop time for the fast stop function that can be triggered either via a digital input, the
bus control, the keyboard or automatically in case of a fault.
Quick stop time is the time for the linear frequency decrease from the set maximum frequency
(P105) to 0Hz. If an actual setpoint <100% is being used, the quick stop time is reduced
correspondingly.

In the standard setting (P428 =
0
Æ
Off
) the inverter requires a flank for enable (signal change
from "low
Æ
high") at the applicable digital input.
In the setting
On
Æ
1
the FI reacts to a high level. This function is only possible if the FI is
controlled using the digital inputs. (see P509=0/1)
In certain cases, the FI must start up directly when the mains are switched on. This means that
P428 =
1
Æ
On
can be set. If the enable signal is permanently switched on, or equipped with a
cable jumper, the FI starts up immediately.
P429
Fixed frequency 1
P
-400 ... 400 Hz
[ 0 ]
Following actuation via a digital input and enabling of the FI (right or left), the fixed frequency is
used as a setpoint. A negative setting value will cause a direction change (based on the
Enable
rotation direction
P420 – P425, P470).
If several fixed frequencies are actuated at the same time, then the individual values are added
with the correct sign. This also applies to combinations with the jog frequency (P113), analog
setpoint (if P400 = 1) or minimum frequency (P104).
The frequency limits (P104 = f
min
, P105 = f
max
) cannot be over or undershot.
If none of the digital inputs are programmed for enable (right or left), the simple fixed frequency
signal leads to an enable. A positive fixed frequency corresponds to a right enable, a negative to
a left enable.
