11.7 Bus CAN (CANfagor/CANopen protocols).
CANfagor and CANopen are network communication protocols based on the CAN bus, for
connecting the CNC with remote modules and keyboards. The CAN connection supports
up to 32 devices (nodes), including the central unit; more one than keyboard and several
groups of remote modules are possible.
CAN connector.
The cable shield must be connected to the connector at both ends. The connector has two
shield pins. Both pins are equivalent and the CAN shield may be connected to either one.
CAN cable characteristics.
Use a specific CAN cable. The ends of all the wires and the shield must be protected by the
corresponding terminal (pin). Also use the terminals (pins) to secure the cable to the
connector.
Module interconnection.
Respect the cable's minimum bending radius when connecting it. They must be connected
in series; on elements having two CAN connectors, either one may be used. Once the
elements have been connected, define their logic order in the bus and the transmission
speed.
General characteristics.
Type. Shielded. Twisted pair (1 x 2 x 0.22 mm²).
Flexibility. Extremely flexible. Minimum bending radius, static = 50 mm and
dynamic = 95 mm.
Cover. PUR
Impedance. Cat.5 (100 - 120)
The drawing shows the CAN connection between the CPU (central unit), the operator panel and 2
groups of RIOR or RIO5 series remote modules.
Plug-in part. 5-pole Phoenix-contact minicombicon connector (3.5 mm
pitch).
Pin. Signal. Function.
1 GND Ground / 0 V.
2 CL (LOW) bus signal.
3 SH CAN shield.
