·S42· CAN bus. Communication speed selection.
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· (CO BR).
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.
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.
·S43· CAN bus. Line terminating resistor.
The line terminating resistor identifies which are the elements
that occupy the ends of the CAN bus; i.e. 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).
DS ·2· DS·3· Speed Length of the CAN bus.
on on 1000 kHz Up to 20 meters.
off on 800 kHz From 20 to 40 meters.
on off 500 kHz From 40 to 100 meters.
off off 250 kHz From 100 to 500 meters.
