Address Input Selection
The Modbus RTU option card interface to
the 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
6000 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 6000 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.
