6.2.7 Baldor CAN
Symptom Check
The Baldor CAN bus is
‘passive’ This means that the internal CAN controller in the
NextMove ST is 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 ST should recover from the ‘passive’ state
once the problem has been rectified.
The Baldor CAN bus is ‘off’ This means that the internal CAN controller in the
NextMove ST has experiencing 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 ST.
