Copley Controls  30 
2.7: Communication 
As described below, the drive features multiple communication interfaces, each used for different 
purposes. 
Interface 
Description 
RS-232 port 
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 2 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. 71). For RS-232 port wiring instructions, see   
RS-232 Serial Communications (p. 95). 
Note that CME 2 can be used to make adjustments even when the drive is being 
controlled over the CAN interface or by the digital inputs. 
CAN interface (XPL/XP2) 
When operating as a CAN node, the drive takes command inputs over a CANopen 
network. CAN communications are described in the next section. 
EtherCAT (XEL/XE2/800-
1782) 
XEL/XE2/800-1782 accepts CANopen commands over EtherCAT. 
MACRO (XML/800-1808) 
The XML/800-1808 typically runs in torque mode accepting commands over the 
MACRO network. (Velocity mode is also supported.) 
DANGER 
Using CME 2 can affect or suspend CAN operations. 
When operating the drive as a CANopen node, use of CME 2 to change drive 
parameters can affect CANopen operations in progress. 
Using CME 2 to initiate motion can cause CANopen operations to suspend. The 
operations may restart unexpectedly when the CME 2 move is stopped. 
Failure to heed this warning can cause equipment damage, injury, or death.
