OMMUNICATIONS
The drives support multiple communication interfaces, each used for different purposes.
Interface
Description
EtherCAT
(AEV, AEZ)
Drives support CANopen application protocol over EtherCAT (CoE)
via a 100BASE-TX physical layer.
CAN interface
(APV, APZ)
When operating as a CAN node, the drive takes command inputs over a
CANopen network. CAN communications are described in the next section.
RS-232 Serial
The RS-232 port is a three-wire, DTE, full-duplex port.
Control commands can be sent over the RS-232 port using Copley Controls
ASCII interface commands.
In addition, CME software communicates with the drive (using a binary
protocol) over this link for drive commissioning, adjustments, and
diagnostics.
Note that CME can be used to make adjustments even when the drive is
being controlled over the CAN interface or by the digital inputs.
DANGER
Using CME can affect or suspend CAN operations.
When operating the drive as a CANopen node, use of CME to change drive
parameters can affect CANopen operations in progress.
Using CME to initiate motion can cause CANopen operations to suspend. The
operations may restart unexpectedly when the CME move is stopped.
Failure to heed this warning can cause equipment damage, injury, or death.
