Setting up communication through the Standard Modbus Link
An RMBA-01 Modbus Adapter installed in slot 1 or 2 of the drive forms an interface
called the Standard Modbus Link. The Standard Modbus Link can be used for
external control of the drive by a Modbus controller (RTU protocol only).
Before configuring the drive for Modbus control, the adapter module must be
mechanically and electrically installed according to the instructions given in the
hardware manual of the drive, and the module manual.
The following table lists the parameters, which need to be defined when setting up
communication through the standard Modbus link.
After the communication parameters in group 52 STANDARD MODBUS have been
set, the drive control parameters (section
on page
)
must be checked and adjusted where necessary.
