Check
This means that the internal CAN controller in the
NextMove ESB-2 is experiencing a number of Tx and/or
Rx errors, greater than the passive threshold of 127.
Check:
12-24 V is being applied to pin 5 of the RJ45 CAN

connector, to power the opto-isolators.
There is at least one other Baldor CAN node in the

network, with jumpers JP1 and JP2 in the '1' (lower)
position.
The network is terminated only at the ends, not at

intermediate nodes.
All nodes on the network are running at the same baud

rate.
All nodes have been assigned a unique node ID.

The integrity of the CAN cables.

The NextMove ESB-2 should recover from the 'passive'
state once the problem has been rectified.
This means that the internal CAN controller in the
NextMove ESB-2 has 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.


To recover from the 'off' state the bus must be reset. This
can be done using the Mint BUSRESET keyword, or by
resetting the NextMove ESB-2.
