List of the possible functions of the digital inputs P420 [01]... [-04]
Value Function Description Signal
00 No function Input switched off. ---
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 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 Change of rotation direction Causes the rotation field to change direction in combination with
Enable right or left. High

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

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

Fixed frequency 3 The frequency from P465 [03] is added to the actual setpoint value. High

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 Param set switching
"Parameter set switchover 1"
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.

Disable voltage The FI output voltage is switched off; the motor runs down freely. Low

Emergency stop The FI reduces the frequency according to the programmed fast
stop time P426.

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

19 Setpoint 1 on/off 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)
