List of possible digital functions for the analog outputs P418
(only POSICON functions)
All relay functions described in Parameter >Function Relay 1< P434 can also be transferred via the analog
output. If a condition has been fulfilled, then there will be 10V at the output terminals. Negation of the function
can be set in parameter >Analog output standardisation< P419.

Up to 10 inputs which can be freely programmed with digital functions are available in the SK
54xE. Of these inputs, analog inputs 1 and 2 of the frequency inverter do not comply with
EN61131-2 (Type 1 digital inputs).
[-01] = Digital input 1 (DIN1): Enable right, (default), Terminal 21
[-02] = Digital input 2 (DIN2): Enable left, (default), Terminal 22
[-03] = Digital input 3 (DIN3): Parameter switching, (default), Terminal 23

4
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.
5
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).
6
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.
