Configuration

Configuration of the module is mainly performed via the DIP switches. The DIP switches are read after
a "power on" of the module. A change to the DIP switch during operation has no effect.

The system bus must be terminated at both of its physical ends (if necessary set the "System bus
termination resistor" DIP switch).

Note

Broadcast mode

In "Broadcast mode, which is activated via the parameter (P162), the module can access up to 4 inverters in
parallel. Therefore the frequency inverters jointly access the I/Os and evaluate the input signals according to their
own parameterisation. Output signals from the frequency inverters which are sent to the common IO module are
linked by a logical "OR" within the module. i.e. a digital output is set as soon as one of the four frequency inverters
addresses it. In addition, the highest analog value is provided via the analog output of the IO extension.
