22 Overview of the RS-485 network and the FSCA-01 module
FSCA-01 RS-485 adapter module
The FSCA-01 RS-485 adapter module is an optional device for
ABB drives which enables the connection of the drive to an
RS-485 network. The adapter module provides galvanic isolation
between the drive and RS-485 network and converts the serial
communication signals of the drive to the RS-485 signal levels.
The adapter module has a built-in bus termination with fail-safe
circuitry. The termination can be activated with a jumper. For
instructions, see chapter
Electrical installation
.
Through the adapter module you can:
•
give control commands to the drive (for example, Start, Stop,
Run enable)
•
feed a motor speed or torque reference to the drive
•
give a process actual value or a process reference to the PID
controller of the drive
•
read status information and actual values from the drive
•
change drive parameter values
•
reset a drive fault.
The communication protocol used to access these functionalities
over the RS-485 connection is described in chapter
Communication protocol
.
The adapter module is mounted into an option slot on the motor
control board of the drive. See the drive manuals for module
placement options.
