Enabled right
The FI delivers an output signal with the rotation field right if a
positive setpoint is present.

Enabled left
The FI delivers an output signal with the rotation field left if a
positive setpoint is present. 0

High
If the drive is to start up automatically when the mains is switched on (P428 = 1) a permanent High level for
enabling must be provided (supply control terminal 21 with 24V).
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
03
Change rotation direction
Causes the rotation field to change direction, combined with
Enable right or left.
High

Fixed frequency 1
The frequency from P465 [01] is added to the actual setpoint value.

Fixed frequency 2
The frequency from P465 [02] is added to the actual setpoint value.

Fixed frequency 3
The frequency from P465 [03] is added to the actual setpoint value.
High
07
1
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, then they are added with the correct sign. In
addition, the analog setpoint (P400) and possibly the minimum frequency (P104) are added.
08
Parameter set switch Bit 0
Selection of the active parameter set 1…4 (P100)
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
10
2
Block voltage
The FI output voltage is switched off; the motor runs down freely.
Low

2
Emergency stop
The FI reduces the frequency according to the programmed quick
stop time (P426).
Low
12
2
Error acknowledgement
Error acknowledgement with an external signal. If this function is
not programmed, an fault can also be acknowledged by a low
enable setting (P506).

PTC resistor input
Only with the use of a temperature monitor (bimetal switching
contact). Switch-off delay = 2sec, warning after 1 sec.

Remote control
With bus system control, low level switches the control to control
via control terminals.

The fixed frequency value can be adjusted using the
HIGHER/LOWER and OK keys (P113), if control is via the
SimpleBox or ParameterBox.

the minimum frequency P104 and above the maximum frequency
P105.

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

Setpoint 1 on/off
Only with I/O extension SK CU4-/TU4-IOE. The relevant analog
input is switched on with a High signal. The Low signal sets the
current setpoint value to 0%, which results in a corresponding
output frequency if a minimum frequency is set in P104.
