4.2.6 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 339.
*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.
