Copley Controls 33
2.4: Communication
As described below, the drive features multiple communication interfaces, each used for different
purposes.
The drive features a three-wire RS-232 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. For RS-232
port specifications, see Serial Interface (p. 76). For RS-232 port wiring instructions,
see
RS-232 Serial Communications (p. 106).
Note that CME can be used to make adjustments even when the drive is controlled
over the CAN or EtherCAT interface, or by the digital inputs.
When operating as a CAN node, the drive takes command inputs over a CANopen
network. .
EtherCAT (XEL/XE2/800-
1818/800-1819/800-1887)
XEL/XE2/800-1818/800-1819/800-1887 accepts CoE (CANopen protocol over
EtherCAT) commands over EtherCAT.
The XML/XM2 typically runs in torque mode accepting commands over the
MACRO network. (Velocity mode is also supported.)
Using CME can affect or suspend CAN or EtherCAT operations.
When operating the drive as a CANopen or EtherCAT node, use of CME to change
drive parameters can affect CANopen operations in progress.
Using CME to initiate motion can cause CANopen or EtherCAT 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.
