3 different commands are used for communication between the inverter and
external units:
a. Read command: external units to read the memory address of the inverter.
b. Write command: external units to write the memory address of the inverter in
order to control the inverter.
c. Circuit test command: To test the communication status between the inverter
and external units.
•
The change of setting Sn-36, Sn-37, Sn-38 will be effective in the next start time
after turning off the inverter.
•
Do not make the DRIVE/PRGM changeover while writing the date into the inverter
through RS-485 port.
•
For more details of RS-485 communication, refer to
“RS-485 MODBUS/PROFIBUS Communication Application Manual”.
