7.2.7 Baldor CAN
	Symptom	Check
	The Baldor CAN bus	This means that the internal CAN controller in the NextMove ES is
	is ‘passive’	experiencing a number of Tx and/or Rx errors, greater than the
		passive threshold of 127.
		Check:
		H 12-24V is being applied to pin 5 of the RJ45 CAN
		connector, to power the opto-isolators.
		H There is at least one other Baldor CAN node in the
		network, with jumpers JP1 and JP2 in the ‘1’ (lower)
		position.
		H The network is terminated only at the ends, not at
		intermediate nodes.
		H All nodes on the network are running at the same
		baud rate.
		H All nodes have been assigned a unique node ID.
		H The integrity of the CAN cables.
		The NextMove ES should recover from the ‘passive’ state once the
		problem has been rectified.
	The Baldor CAN bus	This means that the internal CAN controller in the NextMove ES has
	is ‘off’	experienced a fatal number of Tx and/or Rx errors, greater than the
		off threshold of 255.
		At this point the node will have switched itself to a state whereby it
		cannot influence the bus.
		Check:
		H 12-24V is being applied to pin 5 of the RJ45 CAN
		connector, to power the opto-isolators.
		H There is at least one other Baldor CAN node in the
		network, with jumpers JP1 and JP2 in the ‘1’ (lower)
		position.
		H The network is terminated only at the ends, not at
		intermediate nodes.
		H All nodes on the network are running at the same
		baud rate.
		H All nodes have been assigned a unique node ID.
		H The integrity of the CAN cables.
		To recover from the ‘off’ state the bus must be reset. This can be
		done using the MintMT BUSRESET keyword, or by resetting the
		NextMove ES.
