Using this parameter an adjustment can be made to the analog output for the selected operating
zone. The maximum analog output (10V) corresponds to the standardisation value of the
appropriate selection.
If therefore, at a constant working point, this parameter is raised from 100% to 200%, the analog
output voltage is halved. 10 Volt output signal then corresponds to twice the nominal value.
For negative values the logic is reversed. An actual value of 0% will then produce 10V at the
output and -100% will produce 0V.

In the SK 2xxE, up to 4 freely programmable digital inputs are available. The only restriction is
with the versions SK 21xE and SK 23xE. Here, the fourth digital input is always the input for the
function "Safe Stop".
[-01] = Digital input 1 (DIN1), Enable right as factory setting,
control terminal 21
[-02] = Digital input 2 (DIN2), Enable left as factory setting,
control terminal 22
[-03] = Digital input 3 (DIN3), Fixed frequency 1 (P465 [-01]) as factory setting,
control terminal 23
[-04] = Digital input 4 (DIN4), Fixed frequency 2 (P465 [-02]) as factory setting, not with SK
215/235E "Safe Stop", control terminal 24
Various functions can be programmed. These can be seen in the following table.
By means of an OR link of the parameterised functions and the rotary encoder evaluation, which is
always active in the inverter, it is essential to switch off the functions of the digital inputs DIN 2 and
DIN 3 for the use of a rotary encoder (Parameter (P420 [-02, -03])).
The additional digital inputs of the I/O- extensions (SK xU4-IOE) are administered via the
parameter "Bus I/O In Bit (
4…7)“ - (P480 [-05] … [-08]) for the first I/O extension, and via the
parameter "Bus I/O In Bit (0…3)" - (P480 [-01] … [-04]) for the second I/O extension.

01
Enabled right
The FI delivers an output signal with the rotation field right if a
positive set
point is present. 0 → 2 Flank (P428 = 0)
High
02
Enable left
The FI delivers an output signal with the rotation field left if a
positive setpoint is present. 0 → 2 Flank (P428 = 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 terminal 21 with 24V).
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
If the frequency inverter is in fault status but the cause of the fault no longer exists, the error message is
acknowledged with a
1 → 0 flank.
03
Phase seq. reversal
(Change rotation direction)
Causes the rotation field to change direction in combination with
Enable right or left.
