7.7 Frequency setting
Goodrive200A series 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.
Goodrive200A series inverters support the shifting between different reference channels and
the detailed shifting rules is as below:
