Parameter Setting value / Description / Note Available with option
P426 (P) Quick stop time always visible
0 ...320.00 s
[ 0.1 ]
or [ 1.0 ]
Braking time setting for the emergency stop function, which can be triggered by digital input, bus
control, keyboard or automatically in the case of an error.
Emergency 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 emergency stop time is reduced
correspondingly.
P427 Quick stop on error always visible
0 ... 3
[ 0 ]
Activation of automatic emergency stop following error
0 = OFF: Automatic emergency stop following error is deactivated
1 = On mains failure: Automatic emergency stop following mains supply failure
2 = On errors: Automatic emergency stop following fault
3 = Error on mains supply failure: Automatic emergency stop following mains supply failure and
error
P428 (P) Automatic starting always visible
0 ... 1
[ 0 ]
In the standard setting (P428 = 0  Off) the inverter requires a flank for enable (signal change from
"low  high") at the applicable digital input.
In the setting On  1 the FI reacts to a high level.
In certain cases, the FI must start up directly when the mains are switched on. This means that P428 =
1  On can be set. If the enable signal is permanently switched on, or equipped with a cable jumper,
the FI starts up immediately.
This function is only possible if the FI is controlled using the digital inputs. (siehe P509)
P429 (P) Fixed frequency 1 BSC STD MLT BUS
-400 ... 400 Hz
[ 0 ]
Settings for the fixed frequency.
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).
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, negative left enable.
