Programmable digital inputs 1 to 5
You can assign various functions to terminals 1 to 5. Depending
on your requirements, these terminals can be configured as
follows:
• clockwise start signal (FWD),
• anticlockwise start signal (REV),
• selection inputs for various fixed frequencies (FF1 to FF4),
• reset input (RST),
• etc.
The terminal function for each of the programmable digital inputs
1 to 5 occurs via PNU C01 to C05, i.e. you use PNU C01 to specify
the function of digital input 1, PNU C02 to specify the function of
digital input 2, etc. You cannot, however, assign the same function
to two inputs.
Programmable digital inputs 1 to 5 are configured as make
contacts by default. If, therefore, the function of an input terminal
is to be activated, the corresponding input must be closed (i.e. the
input terminal is connected to terminal P24). Conversely, to deac-
tivate the input terminal, the input must be opened.
Table 10: Digital inputs 1 to 5
A detailed description of the input functions can be found on the
pages listed in Table 11.
Tabelle 11: Functions of the digital inputs
If required, the digital inputs can be configured as break (NC)
contacts. For this purpose, under PNU C11 to C15 (corresponding
to digital inputs 1 to 5), 01 is to be input. An exception exists only
for inputs which you configure as RST (reset) or as PTC (PTC ther-
mistor input). These inputs can only be operated as make (NO)
contacts.

Caution!
If an EEPROM error occurs (fault message E08), all
parameters must be checked to ensure that they are
correct (particularly the RST input).

Caution!
If you reconfigure digital inputs configured as FWD or REV
as break contacts (the default setting is as a make
contact), the motor starts immediately. They should only
be reconfigured as break contacts when it is absolutely
essential.
