If neither of the digital inputs is programmed for left or right enable, then the actuation of a fixed frequency or jog frequency will

enable the frequency inverter. The rotation field direction depends on the sign of the setpoint.

Also effective for Bus control (RS232, RS485, CANbus, CANopen, DeviceNet, Profibus, InterBus, AS-Interface)

With SK 2x5 devices the frequency inverter control unit must be supplied with power for a further 5 minutes after the last change

to the motor potentiometer in order to permanently save the data.

Function cannot be selected via BUS IO In Bits

P426

Quick stop time

(Quick stop time)

0 ... 320.00 s

{ 0.10 }

Setting of the stop time for the quick 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.

P427

Quick stop on error

(Emergency stop on error)

0 ... 2

{ 0 }

Activation of automatic emergency stop following error

0 = Disabled: Automatic quick stop following error is deactivated

1 = reserved

2 = Enabled: Automatic quick stop following fault

P428

Automatic starting

(Automatic starting)

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. 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  On can be set. If the enable signal is permanently switched on, or equipped with a
cable jumper, the FI starts up immediately.

NOTE:

The "Automatic start" function can only be used if a digital input of the frequency
inverter (DIN

1 … DIN 4) is parameterised to the function "Enable right" or "Enable

left" and this input is permanently set to "High". The digital inputs of the
Technology Unit modules (e.g.: SK CU4 - IOE) do not support this "automatic start"
function.

NOTE:

The "Automatic start" can only be activated if the frequency inverter has been
parameterised to local control ((P509) setting { 0 } or { 1} ).
