10.3 Selecting the baudrate 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 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.
Selecting the speed at the CNC.
The CNC detects the transmission speed (baudrate) automatically by asking the rest of the
nodes connected to it.
Speed selection at the operator panels and the keyboard.
The speed is selected with switches ·2· and ·3· (CO BR). 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.
Speed selection at RIO5 remote modules.
The communication at 250 kHz is not available at the RIO5 series remote modules.
Speed selection at RIOW remote modules.
To select the speed of the node, the module must be in configuration mode (all the
dipswitches in the ·off· position). After turning the module on in configuration mode, the top
4 LED's of the module blink indicating the speed selected at the module. The STOP LED
corresponds to dipswitch ·1·, the RUN to dipswitch ·2·, the TX to dipswitch ·3· and the RX
Speed Length of the CAN bus.
1000 kHz Up to 20 meters.
800 kHz From 20 to 40 meters.
500 kHz From 40 to 100 meters.
250 kHz From 100 to 500 meters.
The speed of 250 kHz is only available to communicate with the keyboards and
RIOW series remote modules; this speed is not available at the RIO5 series
remote modules.
The speed is selected with the ·SPEED· switches.
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.

The dipswitch may be used to select the address of the node and
the transmission speed.

The dip-switch of the previous figure corresponds to the RIOW-CANOPEN-ECO module. The dip-
switch of the RIOW-CANOPEN-ECO and RIOW-CANOPEN-STAND modules is the same but rotated
180º, so the ·ON· position is inverted between them.
