Stepper Motor in Single CAN BUS Network
Standalone Operation
When working standalone, user can use the wiring scheme.
For long distance transfer, both ends of the CAN bus should be terminated with120Ω terminating resistors.
As converter has a build-in terminating resistor, user only needs to attach a resistor at the other end
of the bus. Please refer to the manual for how to enable the converter’s terminating resistor.
CANH and CANL should use a twisted wire pair.
Except supply voltage port and motor terminal, voltage on port must be kept between -0.3 ~ 5.3V.
Stepper Motors CANBUS Network
Network Operation
CAN bus provides a reliable and simple method of network constructing.
A wiring scheme is presented for such network operation with one RS232/CAN
converter connected with multiple controllers. For detailed terminal wiring
on each controller.
All nodes are connected onto a twist wire pair.
Star connection scheme must be avoided.
The stub must not exceed 2cm each (The shorter, the better).
Both ends of the bus should be terminated with120 Ω terminating resistors.
Shielded 120 ohm CAN bus cable is recommended if the transfer distance is over 50 meters.
In practice only one terminating resistor is need at the other end of
CAN bus since Controller already has a built-in terminating resistor. To activate
this built-in terminating resistor.
