13.8.2 Identification of the first and last elements of the bus. Line terminating
resistor.
In the CAN bus, it is necessary to use a line terminating resistor to identify which are the
elements that occupy the ends of the bus; i.e. the first and last physical element in the
connection. For the central unit, the terminating resistor is factory installed because the CNC
is always at one end of the bus
13.8.3 CAN bus type selection (CANfagor/CANopen).
Switch ·1· of the DIP switch selects the type of CAN bus.
13.8.4 Selecting the speed for the CANfagor bus.
When using the CANfagor protocol, the transmission speed at the bus is defined at the CNC
(parameter CANLENGTH).
13.8.5 Selecting the speed for the CANopen bus.
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 speed is selected with switches ·2· and ·3·
of the DIP switch and it 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, RIOW and RIOW
series remote modules; this speed is not available at the RIO5 series remote modules.
In order for any change of speed to be assumed, the corresponding module must be reset;
however, we recommend to change the speed while the modules and the CNC are off.
In the other elements, the ·LT· switch identifies which are the
elements that occupy the ends of the CAN bus; that is, the first
and last physical element in the connection. The terminating
elements must have the resistor activated (position 1) but not
the rest of the elements (position 0).
