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 (code 07) in the DRV group to 6 (Int 485) and use
the RS-485 signal input terminals (S+/S-/SG) for communication. Refer to 7 RS-485
Communication features on page 354.
*If AP1-40 is set to ‘4(Serve Drv)’, MaxComID is ‘8’, and if COM-02 is set to ‘4(BACnet), MaxComID is
‘127’. Otherwise MaxComID is ‘250’.
** COM-02 is automatically set to ‘6(Modbus Master)’ when AP1-40 is set to ‘2 or 3’. Otherwise a
user can set the parameter value at user’s choice.
