4.5.4.3 Configuration
The most important functions (functions of sensor / actuator signals via the AS Interface and the "on
board potentiometers" P1 and P2 (only SK 2x0E size 4 and SK 2x5E)) can be set at the frequency
inverter via DIP4 and DIP 5 of DIP switch block S1 ( Section 4.3.2.2 "DIP switches (S1)").
Alternatively, the functions can also be assigned via the arrays [-01] … [-04] of parameters (P480) and
(P481) ( Section 5 "Parameter"). Settings that are made in these parameters only become effective
if DIP switch S1: (DIP4 and DIP5) are in Position "0" ("OFF").
The functions of the integrated potentiometers P1 and P2 (SK 2x0E size 4 and SK 2x5E only) can be
adapted in parameter (P400).
Information
DIP switch
With the DIP switch default settings (S1: DIP4/5 = "0" ("off")) the digital inputs of the frequency inverter are active.
However, as soon as one of the two DIP switches is moved to position "I" ("ON"), the
deactivated. However, the gateway function of digital inputs 1 and 2 on AS-i-Out bits 2 and 3 is retained.
Information
Overloading of the 24V supply
When using the AS-Interface, this affects devices of type SK 2x5E (not special version SK 225E-…-AUX and
…-AXB)
Because of the low load reserves of the low voltage when using the AS interface, it is advisable to parametrise
the frequency inverter with the aid of the NORDCON software. The use of a parametrisation box (SK PAR-3H /
SK CSX-3H) can cause damage to the frequency inverter, particularly during long periods of operation.
