E.1: Single-Axis and Multi-Drop
An XPL/XP2 drive’s RS-232 serial bus can be used by CME for drive commissioning. The serial bus
can also be used by an external control application (HMI, PLC, PC, etc.) for setup and direct serial
control of the drive. The control application can issue commands in ASCII format.
For experimentation and simple setup and control, a telnet device such as the standard Microsoft
Windows HyperTerminal can also be used to send commands in ASCII format. For more information,
see Copley Controls ASCII RS-232 User Guide.
The serially connected drive can also be used as a multi-drop gateway for access to other drives
linked in a series of CAN bus connections.
Instructions for hooking up a single-axis connection and a multi-drop network appear below.
E.1.2: Single-Axis Connections
For RS-232 serial bus control of a single axis, set the CAN node address of that axis drive to zero
(0). Note that if the CAN node address is switched to zero after power-up, the drive must be reset
or power cycled to make the new address setting take effect.
E.1.3: Multi-Drop Network Connections
A serially connected XPL/XP2 drive can be used as a multi-drop gateway for access to other
XPL/XP2 drives linked in a series of CAN bus connections. Set the CAN node address of the serially
connected drive (gateway) to zero (0). Assign each additional drive in the chain a unique CAN node
address value between 1 and 127. If the XP2 is used as the master, axis B is sequentially addressed
automatically. Also, when using XP2 as a master, axis A will not be available for CAN controls. Use
120 Ohms termination on the first and last drive.
