5.2.1 Setting the Modbus Baud Rate and Parity

The transmission speed and parity of the CM-232 are set via parameters
Baud Rate
The transmission speed of the CM-232 depends on various application-specific pa-
rameters. For example, the cable length limits the transmission speed due to signal
propagation delays.

Parameter
Description
Normally, it is not necessary to change the default setting (Address 1).
In the case of special operating conditions, the address can be ad-
justed.
An address change is effective immediately, i.e. without a restart of
the frequency inverter.
