Up to 5 freely programmable digital inputs are available. The analogue inputs can also still be
used as digital inputs, but their electrical characteristics are not compatible with the PLC standard.

When an encoder is being used, digital inputs DIN 2 and DIN 3 must be disabled using an OR
operation of the parameterised functionality and the encoder evaluation that are always active in
the inverter (parameter P420 [-02, -03]).
The additional digital inputs of the I/O- extensions (SK xU4-IOE) are managed 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.

Note:
The M12 plug connectors on option slots
M1
-
M8
are used to evaluate sensors. Physically
these are connected to the internal digital inputs, which in turn can be set to certain functions with
parameter
P420
. Normally, the sensor signals are only read in and transmitted via the bus system
via which the FI can then be controlled. The control elements at option slots
H1
and
H2
also use
these inputs. In this case the relevant inputs are pre-parameterised at the factory.

Note:
The default values of parameter P420 [-05], [-06] and [-07] depend on the control elements
on option slots
H1
and

01
Enable right
The FI delivers an output signal with the rotation field right if a
positive setpoint is present: 0 → 1
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 → 1 Flank (P428 = 0)
High
If the drive is to start up automatically when the low voltage is switched on (P428 = 1) a permanent High level
for enabling must be provided.
The FI is blocked if the functions "Enable right" and "Enable left" are actuated simultaneously.
If the frequency controller is in fault status but the cause of the fault is no longer present, the error message is
acknowledged with a
1 → 0 Flank
.
03
Change of rotation direction
Causes the rotation field to change direction (in combination
with enable right or left).

High
If several fixed frequencies are actuated simultaneously, they are added with the correct sign. In addition, the
analogue setpoint (P400) and if necessary the minimum frequency (P104) are added.
