5.5.8 Frequency setting
The TD350 series VFD supports multiple kinds of frequency reference modes, which can be
categorized into two types: main reference channel and auxiliary reference channel.
There are two main reference channels, namely frequency reference channel A and frequency
reference channel B. These two channels support simple arithmetical operation between each other,
and they can be switched dynamically by setting multi-function terminals.
There is one input mode for auxiliary reference channel, namely terminal UP/DOWN switch input. By
setting function codes, users can enable the corresponding reference mode and the impact made on
the VFD frequency reference by this reference mode.
The actual reference of VFD is comprised of the main reference channel and auxiliary reference
channel.
