Communication operation between one inverter and one controller
Set parameters on the controller: Program 08 as CL1, Program 09 as Protocol 2.
Communication operation between one inverter and two controllers
Set parameters on the first controller: Program 08 as CL1, Program 09 as Protocol 2.
Set parameters on the second controller: Program 08 as CL1, Program 09 as Protocol 3.
There will be a RS485/CAN Hub needed to converge the communication cables from the controllers to the inverter.
RS485/CAN Hub:
SIG (default), used to communicate with upper computer
CL1, used to communicate through RS485
CL2, used to communicate through CAN.
RS485

Address
Address 1 (default)
Used to communicate with controller in CL1 or CL2, or used to
communicate with upper computer in SIG
