4.3.2.2 DIP switches (S1)
The DIP switches make it possible to carrying out commissioning without additional control units.
Further settings are made using the potentiometer on the top of the frequency inverter (P1 / P2,
SK 2x5E only).
Information
Factory setting, as delivered!
As delivered, all DIP switches are in the "0" ("off") position. Actuation takes place using the digital control signals
(P420 [01]-[04]) and the potentiometers P1 and P2 integrated in the FI (P400 [01]-[02]) (P1 / P2 with SK 2x5E
only).
IO bit factory settings:
For controlling the frequency inverter via In/Out bits (e.g.: AS-i, DIG In 1 - 4) typical values are pre-set in the
relevant parameters (P480) and (P481) (Details:  Section 5 "Parameter").
These settings apply to both control via AS-i bits and BUS I/O bits.

A changed setting is applied the next time the mains is switched on.
Existing settings in parameters P201-P209 and P105 are overwritten!
up to firmware version 1.4 R1 the DIP switch designation was U/F. A
changeover between the control procedures (U/F / ISD control) has been
made possible via the DIP switch.
