CAN
AXEL provides two CAN interfaces (FLEXCAN1 and
FLEXCAN2) for supporting distributed realtime control with a
high level of reliability. The FLEXCAN module implements the
CAN protocol version 2.0 part B and supports bit rates up to 1
Mbit/s.
7.10.1 FLEXCAN1
FLEXCAN1 port is connected to on-board transceiver (TI
SN65HVD232) which converts the single-ended CAN signals of
the controller to the differential signals of the physical layer.
When required, the on-board transceiver can be excluded by
dedicated mount options. Please contact our Sales Department
for more information about this hardware option.
