Communication Parameters

The following communications parameters affect communication over RS-232, RS-422 and RS-485 networks. The RS-232 communication

parameters are fixed. In addition, the node address is ignored when communicating via RS-232.

H5 group communication parameters can only be changed via the drive keypad.

Note: Drive power must be cycled for changes to H5 Group parameters to be recognized.

RS-232 Communication

The RS-232 communications parameters are fixed at the values shown below. Although the node address is ignored, the master when

communicating to the G7 drive in this method typically uses a node address of 1.

RS-422/RS-485 Communication

Node Address – H5-01

. The node address is set through G7 drive parameter H5-01. When communicating via RS-422 or RS-485, a

unique node address between 0 and 20h (32 decimal), inclusive, must be entered. The default G7 drive address is 1Fh (31 decimal).

The address is always entered as a hexadecimal number (refer to the conversion chart in Chapter 4). Address 0 is typically reserved for

global messages.

Baud Rate – H5-02

. Select the baud rate that matches the controller’s communication configuration.

4 19,200bps

Parity – H5-03

. Select the parity that matches the controller’s communication configuration.
