Analog functions P418 (= 0 ... 6 and 8 … 14, 30)
With this parameter an adjustment can be made to the analog output for the selected working
range. The maximum analog output (10
V) corresponds to the scaling value of the appropriate
selection.
Therefore, if this parameter is raised from 100 % to 200 % at a constant working point, the analog
output voltage is halved. The 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 10
V at the
output and -100 % will produce 0 V.
Digital functions P418 (= 15 ... 28, 34...52)
The switching threshold can
be set using this parameter for the functions Current limit (= 17),
Torque current limit (= 18) and Frequency limit (= 19). A value of 100
% refers to the
corresponding motor nominal value (see also P435).
With a negative value, the output function is output negated (0/1 → 1/0).

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).

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 an 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.
