Overview
16
The maximum length of trunk cable depends on the data rate and
on the type of the cable used (see chapter
Technical data
).
Terminating resistor
The DeviceNet network should be terminated at both ends of the
trunk cable with a 121 ohm, ¼ W, 1% Metal Film resistor. Connect
this resistor between the two signal wires (CAN_H, CAN_L) on the
DeviceNet cable.
The RDNA-01 DeviceNet Adapter module
The RDNA-01 DeviceNet Adapter module is an optional device for
ABB drives which enables the connection of the drive to a
DeviceNet system. The drive is considered as a slave in the
DeviceNet network. Through the RDNA-01 DeviceNet Adapter
module it is possible to:
• give control commands to the drive
(Start, Stop, Run enable, etc.)
• 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
• read and write drive parameter values
• reset a drive fault.
The RDNA-01 acts as a Class 2 slave only with predefined
master-slave connection set services. These include the Explicit
Messaging, the Poll-Response service and the Change of State/
Cyclic service. The DeviceNet commands and services supported
by the RDNA-01 DeviceNet Adapter module are discussed in
chapter
Communication
. Please refer to the user documentation
of the drive as to which commands are supported by the drive.
