[ 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.
The 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 Emergency 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 = Mains supply failure: Automatic emergency stop following mains supply failure
2 = Error: Automatic emergency stop following fault
3 = Mains supply failure and error: Automatic emergency stop following mains supply failure

[ 0 ] In the standard setting (P428 = 0

Off) the inverter requires a flank to enable (signal change from
"Low

High") at the relevant digital input.
In the setting On

1, the FI reacts to a High level. This function is only possible if the FI is controlled
using the digital inputs. (see P509).
In some cases, the FI must start up directly when the mains are switched on. For this 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.
