The Modbus RTU option card interface to the
VLT 5000 and VLT 6000 Adjustable Frequency
Drive FC protocol requires drive parameter
values selected as shown. They are the default
settings for those parameters and probably
require no change to operate the drive using
Modbus. The Modbus RTU option card always
transmits to the drive in which it resides as
address one (001). See the VLT Operating
Instructions for details on selecting and
changing parameter values, if necessary.

The Modbus RTU option card has an address
and termination 9-input dip switch. The Modbus
network address for the VLT is set by dip switch
positions on the switch. Pin 9 is an ON/OFF
switch for network termination. DIP switch
positions are read on power-up only, so position
changes will not be recognized until the next
power-up.
