4.5.4.3
Configuration
The most important functions (functions of sensor/actuator signals via the AS interface and on-board
potentiometers
P1
and
P2
(only SK 2x0E size 4 and SK 2x5E)) can be set on the variable frequency
drive via DIP4 and DIP 5 of DIP switch 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 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 variable frequency drive are
active.
However, as soon as one of the two DIP switches is moved to position I (ON), the digital inputs are 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 parameterize
the variable frequency drive with the aid of NORD CON software. The use of a parameterization unit
(SK PAR-3H/SK CSX-3H) can cause damage to the variable frequency drive, particularly during long periods of
operation.
