Establishing Communication

Establish communication between the drive connected to the 1203-USB
converter and the computer.

Configuring the Drive Parameters

When setting drive parameters for the functions listed in the following
subsections to enable operation on an RTU Master serial multi-drop
network, use any of the following tools:

• The integral keypad on each DSI drive (if available)

• The 1203-USB converter and Connected Components Workbench

software

When using the converter, electrically connect the converter to the computer
and the first drive, establish communication with the drive, and use a drive
software tool to set its parameters. Then electrically connect the converter to
the next drive and repeat the process until the parameters in all of the drives
have been set.

Setting Comm Data Rates

For each drive to be networked, including Drive 1 connected to the
1203-USB converter, use the following drive parameter and value to set the
communication data rate to 19.2K baud.

• PowerFlex 4-Class drives: Parameter 103 [Comm Data Rate] = ‘4’

• PowerFlex 520-Series drives: Parameter 123 [RS485 Data Rate] = ‘4’

Setting Drive Addresses

1. For Drive 1 connected to the 1203-USB converter, use the following

drive parameter to set the drive’s RS485 node address to match the
converter node address (default = 1 and set with converter Parameter
06 - [RTU DSI Addr Cfg])
.
