Description
Signal
If the drive is to start up automatically when the line voltage is switched on (P428 = 1), a permanent high level
must be provided for enabling (supply control terminal 21 with 24 V).
If the "Enable right" and "Enable left" functions re actuated simultaneously, the VFD is blocked.
If the variable frequency drive is in fault status but the cause of the fault no longer exists, the error message is
acknowledged with a
1 → 0 flank
.

Phase seq. reserval
Causes the rotation field to change direction in combination with
Enable right or left.

The frequency from P465 [01] is added to the actual setpoint
value.

Fixed frequency 4
The frequency from P465 [04] is added to the actual setpoint
value.
High
If several fixed frequencies are actuated at the same time, they are added with the correct sign. In addition,
the analog setpoint (P400) and if necessary the minimum frequency (P104) are added.

Para Set Switching
"Parameter set changeover 1

Selection of active parameter set 1…4 - first bit.
High
09
Hold frequency
During the acceleration or deceleration phase, a low level will
cause the actual output frequency to be "Held". A high level
allows the ramp to proceed.
Low

Voltage disable
The VFD output voltage is switched off; the motor coasts to a
stop.

Quick stop
The VFD reduces the frequency according to the programmed
quick stop time from P426.

Fault acknowledgem.
Fault acknowledgement with an external signal. If this function
is not programmed, a fault can also be acknowledged by a low
enable setting (P506).

The frequency value from (P113) can also be set directly using
the HIGHER/LOWER buttons with a controller, Simple Box or
Parameter Box and stored in (P113) using the OK button.
If the device is operating with inching frequency, any bus
actuation that may be active is deactivated.

Input must see a high flank cyclically (P460), otherwise error
E012 will cause a shutdown. Function starts with the 1st high

Setpoint 1 on/off
SK 2x0E:
Analog input switch-on and switch-off 1/2 (high = ON)
of the variable frequency drive
SK 2x5E:
Analog input switch-on and switch-off 1/2 (high = ON)
of the first I/O extension. The Low signal sets the analog input
to 0% which does not lead to shutdown when the minimum
frequency (P104) > than the absolute minimum frequency
(P505).
