Connecting the Communication Line

1) Connect the RS485 communication line to the drive's (S+), (S-) terminals of the control
terminals.
2) Connect the CM terminal among drives for stable communication.
3) Check the connection and turn ON the drive.
4) Install a repeater to upgrade the communication speed or longer than 1200mm
communication line is used. Repeater is required for upgrading communication quality
in the noise-high environment.
5) If the communication line is connected correctly set the communication-related
parameters as the following:
DRV-03 [Drive mode]: 3(RS485)
DRV-04 [Freq. mode]: 7(RS485)
I60 [Inv. Number]: 1~32 (If more than 1 drive is connected, be sure to use different
numbers for each drive)
I61 [Baud-rate]: 3 (9,600 bps as Factory default)
I62 [Lost Mode]: 0 - No action (Factory default)
I63 [Time-Out]: 1.0 sec (Factory default)
I59 [Comm. Prot]: 0 - Modbus-RTU
