FAQ

Here are some of the most frequently asked questions.

How do I terminate the CAN bus network? Why is this important?

It is necessary to terminate the CAN bus network with external termination resistors. The resistors are 120 Ohm, 0.25W minimum, metal film or similar type. They should be placed between CAN_H and CAN_L terminals at both ends of the network.  Networks with improper termination will not function.

It is also necessary to use a 120 Ohm resistor, 0.25W minimum, metal film or similar type on the CAN side of the Axiomatic USB-CAN converter when flashing new embedded firmware into the Axiomatic controller over the CAN bus.

Are controller baud rates configurable?

Axiomatic controllers with SAE J1939 CAN bus have a non-configurable baud rate of 250 kbit/s to meet the standard J1939/11 and J1939/15. Another part number with a 500 kbit/s is available for some models and these parts meet the standard J1939/14.  Non-standard SAE J1939 with a 1Mbit/s baud rate are also available for some models.  Refer to the Technical Datasheet to see which models offer these options. Speak to the sales representative to request a quotation for the baud rate that you require.

The baud rate in the Electronic Assistant is configurable solely to allow the user to match the baud rate of the controller they are installing.  In most cases, it is 250 kbit/s.  The Electronic Assistant will not change/overwrite the baud rate which is factory set in the controller.  The password to change the baud rate in the Electronic Assistant is ‘ChangeBaudRate’.

CANopen Axiomatic controllers have a configurable baud rate.  This configurable baud rate functionality is inherent in the CANopen standards.

How is the Axiomatic control powered during configuration mode?

The Axiomatic control receives its power during configuration via the Power + and Power – (or Batt + and Batt -) pins on the main connector and connection to a 12V or 24V battery power source.  The USB-CAN converter, used to interface with the Electronic Assistant software tool does NOT provide power to the Axiomatic control.

Where can I obtain the Electronic Assistant software?

Scroll down to the appropriate part number to locate the zipped EDS file for download.

PDF files of the product drawing are available for some part numbers on the user.html page. 3D STEP files are posted there, where available. Drawings are available on request as well.  Contact sales@axiomatic to request a product drawing and specify the format.

Which CANopen service tools work with Axiomatic CANopen controls?

Axiomatic provides an .EDS file for use with the Axiomatic CANopen controllers. These files are available on our website (Refer to FAQ 5.)  Axiomatic does not supply a CANopen interface for object configuration. Axiomatic typically uses an ESD electronics CANopen USB interface.  We also use an ESD electronics application called COBview to change parameters and view objects in the Axiomatic controller. Contact ESD electronics for details.

There are many other CANopen tools available in the marketplace for end users. Here is a list of some other commonly used tools.
