CAN A
RCHITECTURE
As shown below, in a CANopen motion control system, control loops are closed on the individual drives, not across the network.
A master application coordinates multiple devices, using the network to transmit commands and receive status information.
Each device can transmit to the master or any other device on the network. CANopen provides the protocol for mapping device
and master internal commands to messages that can be shared across the network.
CAN A
DDRESSING
A CANopen network can support up to 127 nodes. Each node must have a unique and valid seven-bit address (Node ID) in
the range of 1-127. (Address 0 is reserved and should only be used when the drive is serving as a CME serial port multi-drop
gateway.)
There are several basic methods for setting the CAN address, as described below. These methods can be used in any
combination, producing a CAN address equal to the sum of the settings.
Addressing Method
Use switch
Use inputs
Use programmed

For more information on CAN addressing, see the CME User Guide.

TATUS
There are not status indicators on the AEV or APV modules. However there are status indicators
on the AEZ and APZ EZ board assemblies. Details are provided in
Copley Controls
: APV
Description
If the address number <= 15, CAN address can be set using the CAN ADDR
switch only.
Use the drive's programmable digital inputs (user selects how many (1-7) and
which inputs are used).
Program address into flash only.
