4.1.6 Frequency Reference Source Configuration for RS-485
Communication
Set the Frq (Frequency reference source) code in the Operation group to 6 (Int 485).
Control the inverter with upper-level controllers, such as PCs or PLCs, via RS-485
communication by using RS-485 signal input terminals (S+/S-) of the control terminal
block. Refer to
7 RS-485 Communication Features on page 208 for more details.

4.2 Frequency Hold by Analog Input
If you set a frequency reference via analog input at the control terminal block, you can
hold the operation frequency of the inverter by assigning a multi-function input as the
analog frequency hold terminal. The operation frequency will be fixed upon an analog
input signal.
