Analog I/O cable connections
The analog I/Os of the FCD 302 can be configured to cover most use cases. The default conversion from FCD 300 has a limitation as
there is no input 60 in the FCD 302. If analog input 54 in the FCD 302 is not used for motor thermistor, this input can be configured to
provide the functionality of output 60 in the FCD 300.
