1.1 Purpose of the Manual
The
VLT
®
CANopen MCA 105 Programming Guide
provides
information about configuring the system, controlling the
frequency converter, parameter access, programming, as
well as troubleshooting.
The programming guide is intended for use by qualified
personnel who are familiar with the VLT
®
frequency
converter, with CANopen technology, and with the PC or
PLC that is used as a master in the system.
Read the instructions before programming and follow the
procedures in this manual.

1.4 Product Overview
This programming guide relates to the CANopen interface.

CANopen is a low-level network that standardises
communications between industrial devices (sensors, limit
switches, motor controls) and high-level devices
(controllers). CANopen follows the open systems intercon-
nection (OSI) model and is based on CAN technology for
media access control and physical signalling.
Configure CANopen systems to operate in a master-slave
or a distributed control architecture using peer-to-peer
communication. Up to 127 nodes in a multi-drop network
topology are supported. By using the same cable for
communication, the bus can power the communication
options directly. Nodes can be removed or inserted
without powering down the network.
Each node on the network has its own unique communi-
cation object identifier (COB-ID) to distinguish it on the
network. The access control is based on the CSMA/CA
(carrier sense multiple access/collision avoidance) principle,
meaning that all nodes may have access to the network at
the same time. When 2 nodes attempt to get control of
the network bus simultaneously, the CAN protocol resolves
the issue by arbitration. In this way, collisions on the
network are avoided.
CANopen defines device profiles for devices belonging to
specific classes. For other devices, define a custom class to
make it CANopen compatible. All of the above enhances
the interchangeability and interoperability of the network.
