7.7 Frequency setting

CV50 inverters can set the frequency by various means. The reference channel can be divided into main
reference channel and assistant reference channel.
There are two main reference channels: A frequency reference channel and B frequency reference channel.
These two reference channels can carry out mutual simple math calculation between each other. And the
reference channels can be shifted dynamically through set multi- function terminals.
There are three assistant reference channels: keypad UP/DOWN input, terminals UP/DOWN switch input and
digital potentiometer input. The three ways equal to the effect of input UP/DOWN reference in internal
assistant reference of the inverter. The user can enable the reference method and the effect of the method to
the frequency reference by setting function codes.
The actual reference of the inverter is consisted of main reference channel and assistant reference channel.
