Up to 10 inputs which can be freely programmed with digital functions are available. Of these
inputs, analog inputs 1 and 2 of the frequency inverter do not comply with EN61131-2 (Type 1
digital inputs).

List of the possible functions of digital inputs
Value Function Description Signal
00 No function Input switched off. ---
01 Enable right The device 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 device 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 (bridge
between DIN1 and the control voltage output).
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
If the frequency controller 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, combined with Enable right or left. High
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). 0 à1

1 Up to and including Size 4, digital input 5 is not available. In place of this a potential-free isolated thermistor input is implemented, whose function
cannot be disabled. If no thermistor is present the two terminals TF- and TF+ must be bridged. Parameterisation of this input does not have any
effect.
2 Digital input 7 (DIN7) can also be used as digital output 3 (DOUT3 / Binary output 5). It is recommended that either an input function (P420 [-07]
or an output function (P434 [-05]) is parameterised. However, if and input function and an output function are parameterised, a High signal from
the output function will result in the activation of the input function. This IO-exclusion is hence used as a kind of "flag". This also applies for digital
input 8 (DIN8) and digital output 2 (DOUT2 / binary output 4).
3 The analog inputs 1 and 2 (AIN1 / 2) can also process digital functions. Care must be taken that either an analog function (P400 [ - 01]/[-02]) or a
digital function (P420 [-08]/[-09]) is parameterised in order to prevent misinterpretation of the signals. -
