Setting a Frequency Reference via RS-485 Communication
Control the inverter with upper-level controllers, such as PCs or PLCs, via RS-485
communication. Set the Frq (Frequency reference source) code in the Operation group to 6
(Int 485) and use the RS-485 signal input terminals (S+/S-/SG) for communication. Refer to
