3.4.3.2 Configuration
The configuration of the system bus settings and the functions of the analog inputs and outputs is made via
a 12-part DIP switch element. Both analog inputs are differential inputs. The input voltage is simultaneously
measured in a unipolar and bipolar manner. The evaluation is unipolar or bipolar, according to the DIP
switch setting, with or without offset, as a current or voltage input.
If the module is configured for fail-safe signals in case of cable breaks ( 2…10V / 4 .. 20mA), with signal lev-
els < 1V / < 2mA the frequency inverter switches to the state "Start disabled" (See also P700 [-03]). This
monitoring function is always active, even if the analog inputs are parameterised to "No function".

NOTE
Up to software version V1.0 R1 of the I/O extension the setpoint value of the analog output
could be inverted via DIP switch 12:
DIP12 setting "OFF": 100% setpoint = 10V 0% setpoint = 0V
DIP12 setting "ON": 100% setpoint = 0V 0% setpoint = 10V
With newer versions, this setting is made in parameter (P163) "Inversion AOut".
NOTE
The setting of the DIP switches is only read out during the initialisation phase. Changes
made while running are therefore not taken into account.
The side of the DIP switch element corresponding to "ON" should be checked (see label on
the DIP switch element) as for process reasons, this may vary during the manufacture of
the module.
