CAN1 is opto-isolated and is intended for use as the machine-wide fieldbus using the open protocol CANopen. Practical operation of this CAN channel is limited to 500Kbaud owing to the propagation delay of the opto-isolators.

Correct operation of CAN1 can only be achieved with screened/shielded twisted pair cabling. CAN1+ and CAN1- must form a twisted pair with the shield connected to the connector backshell. CAN1 must be terminated by a 120Ω resistor connected between CAN1+ and CAN1- at both ends of the network and nowhere else.

If the MintDrive is at the end of the network then ensure that the CAN1 DIP switch (located on the front panel) is in the ON position, which will connect an internal terminating resistor. A convenient way of wiring a chain of devices is by using a T-connector.

Note: The CAN1 port must be powered with a DC voltage in the range 12-24V.
