13.3 Installation
13.3.1 Connecting the communication line
Connect the RS485 communication line to the inverter’s (S+), (S-) terminals of the control terminals.
Check the connection and switch the inverter ON.
If the communication line is connected correctly, set the communication-related parameters as
following:

DRV-03 [Drive mode]: 3(RS485)

DRV-04 [Freq. mode]: 7(RS485)

I/O-60 [Inv. Number]: 1~250 (If more than 1 inverters are connected, be sure to use different numbers
for each inverter)

I/O-61 [Baud-rate]: 3 (9,600 bps as Factory default)

I/O-62 [Lost Mode]: 0 - No action (Factory default)

I/O-63 [Time-Out]: 1.0 sec (Factory default)

I/O-59 [Comm. Prot]: 0 - Modbus-RTU, 1 – ES BUS
