CAN bus configuration.

CANMODE
Type of CAN bus.
Possible values: CANfagor / CANopen.
Default value: CANopen.
Associated variable: (V.)MPG.CANMODE
CANfagor bus.
Using the CANfagor type bus requires the definition of the maximum length of the bus with
parameter CANLENGTH.
CANopen bus.
When using the CANopen type bus, the work speed is defined in each node. All the nodes
must work at the same speed. The work speeds at the bus depend on the total length of the
bus.
Length (m)
Speed (KHz)
CANLENGTH
CANfagor bus cable length.
Possible values: Up to 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130 and more than 130 meters.
Default value: Up to 20 meters.
Associated variable: (V.)MPG.CANLENGTH
The work speeds at the bus depend on the total length of the bus.
Length (m)

Speed (KHz)
1000 888
CANOPENFREQ
CANopen bus communication frequency.
Possible values: Autoscan / 1 Mbps / 800 kbps / 500 kbps / 250 kbps.
Default value: Autoscan.
Associated variable: (V.)MPG.CANOPENFREQ
When using the CANopen protocol, the transmission speed at the bus is defined in each node
and they all must run at the same speed. The transmission speed depends on the total length
of the bus. Using the following illustrative values; assigning other values may cause
communication errors due to signal distortion.

The speed of 250 kHz is only available to communicate with the keyboards and RIOW and RIOR series
remote modules; this speed is not available for the RIO5 series remote modules.
Peculiarities of the laser model.
For the laser model with RIOR modules, it is recommended to use a communications
frequency of 1 MHz.

Length of the CAN bus.
The CNC adjusts the bus frequency at every startup depending on the speed of
the rest of the modules. Depending on the configuration of the bus, this option
can make the CNC startup slower than if there is a set frequency.
Up to 20 meters.
From 20 to 40 meters.
From 40 to 100 meters.
From 100 to 500 meters.
