Value Function
Description
Signal
04
Fixed frequency 1
1
The frequency from P429 is added to the actual setpoint value.
High
05
Fixed frequency 2
1
The frequency from P430 is added to the actual setpoint value.
High
06
Fixed frequency 3
1
The frequency from P431 is added to the actual setpoint value.
High
07
Fixed frequency 4
1
The frequency from P432 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
Switchover of parameter sets
First Bit of the parameter set switch over,
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
Block voltage
2
The FI output voltage is switched off; the motor runs down freely.
Low
11
Quick stop
2
The FI reduces the frequency according to the programmed fast stop time from
P426.
Low
12
Error acknowledgement
2
Error acknowledgement with an external signal. If this function is not
programmed, an fault can also be acknowledged by a low enable setting
(P506).

13
PTC input
2
Analog evaluation of signal present. Switching threshold approx. 2.5 V,
Switch-off delay = 2 sec, warning after 1 sec.
NOTE: Fnct. 13 can only be used via DIN 5 up to SK 535E, sizes 1 - 4!
For SK 54xE and sizes above Size 5, there is a separate connection which
cannot be deactivated. If the motor is equipped with a thermistor, for these
devices both terminals must be bridged in order to deactivate the function
(status as delivered).
level
14
Remote control
2, 4
With Bus system control, low level switches the control to control via control
terminals.
High
15
Jog frequency
1
The fixed frequency value can be adjusted using the HIGHER/LOWER and
ENTER keys (P113), if control is via the ControlBox or ParameterBox.
High
16
Motor potentiometer
As in setting 09, however, the frequency is not maintained below the minimum
frequency P104 and above the maximum frequency P105.
Low
17
Para. Set Switchovr. 2
Second Bit of the parameter set switch over, selection of the active parameter
set 1…4 (P100).
High
18
Watchdog
2
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
Analog input switch-on and switch-off 1/2 (high = ON) 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).
High

Setpoint 2 on/off
21
Fixed frequency 5
1
The frequency from P433 is added to the actual setpoint value.

Blocks the >Enable right/left< via a digital Input or bus control. Does not depend
on the actual direction of rotation of the motor (e.g. following negated setpoint).

3-Wire Direction
(Direction reversal button)
3-Wire-Control, this control function provides an alternative to enable R/L (01,
02), in which a permanently applied level is required.
Here, only a control impulse is required to trigger the function. Control of the FI
can therefore be performed entirely with buttons.
A pulse on the function "Reverse direction of rotation" inverts the present
direction of rotation. This function is reset with a "Stop signal" or by activating a
button for the functions 45, 46, 49.

Motorpot.Freq.+
In combination with enable R/L the output frequency can be continuously
varied. To save a current value in P113, both inputs must be at a High voltage
for 0.5 s. This value then applies as the next starting value for the same
direction of rotation (Enable R/L) otherwise start at f
MIN
. Values from other
setpoint sources (e.g. fixed frequencies) are not taken into account.
