CAN bus
The machine controllers communicate with each other on a Controller Area
Network (CAN) bus system; refer to
CAN bus Communications (page 5–12)
for
CAN bus operation notes. Controllers that operate on 12 VDC connect to the
12V side of the CAN bus (CAN A), while controllers that operate on 48 VDC
connect to the 48V side of the CAN bus (CAN B). A 120 ohm CAN termination
resistor is located at each end of CAN A, and at each end of CAN B (4 total);
refer to
CAN bus Terminator Resistors (page 5–101)
.

Testing the CAN bus
1. Make sure that key switch is in the O
FF
position.
2. Remove the right side cover.
