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=0/1)
In certain 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.
NOTE: (P428) not "ON" if (P506) = 6, Danger! (See note on (P506))
NOTE: The "Automatic Start" function can only be used if a digital input of the frequency
inverter (DIN 1 …) is parameterised to the function "Enable Right" or "Enable Left"
and this input is permanently set to "High". The digital inputs of the technology
modules (e.g.: SK CU4 - IOE) do not support this "Automatic Start" function!
NOTE: The "Automatic Start" function can only be activated if the frequency inverter has
been parameterised to local control ((P509) setting { 0 } or { 1} ).

Settings 3 to 5 and 11 operate with a 10% hysteresis, i.e. the output delivers (Funct. 11 does not
deliver) when the limit value 24V is reached and switches this off again when a 10% lower value is
undershot (Funct. 11 on again).
This behaviour can be inverted with a negative value in P435.

1 = External brake, for control of an external 24V brake relay (max. 20 mA). The
output switches at a programmed absolute minimum frequency (P505).
A setpoint delay of 0.2-0.3s (see also P107/P114) should be set for typical
brakes.
Devices with an optional integrated brake rectifier (e.g. Option „-HWR“,
