Note:
All CAN related Mint keywords are referenced to either CANopen or Baldor CAN
using the ‘bus’ parameter. Although the NextMove ES has a single physical CAN
bus channel that may be used to carry either protocol, Mint distinguishes between
the protocols with the ‘bus’ parameter. For CANopen the ‘bus’ parameter must be
set to 1.
Please refer to the Mint help file for further details on CANopen, Mint keywords and parameters.
4.6.4 Baldor CAN
The NextMove ES must have the Baldor CAN firmware loaded to use this protocol.
Baldor CAN is a proprietary CAN protocol based on CAL. It supports only the following range
of Baldor CAN specific I/O nodes and operator panels:
H
InputNode 8 (Baldor part ION001-503) - an 8 x digital input CAN node.
H
OutputNode 8 (Baldor part ION003-503) - an 8 x digital output CAN node.
H
RelayNode 8 (Baldor part ION002-503) - an 8 x relay CAN node.
H
IoNode 24/24 (Baldor part ION004-503) - a 24 x digital input and 24 x digital output CAN
node.
H
KeypadNode (Baldor part KPD002-501) - an operator panel CAN node with 4 x 20 LCD
display and 27 key membrane labeled for control of 3 axes (X, Y, Z).
H
KeypadNode 4 (Baldor part KPD002-505 ) - an operator panel CAN node with 4 x 20 LCD
display and 41 key membrane labeled for control of 4 axes (1, 2, 3, 4).
A typical Baldor CAN network with a NextMove ES and a Baldor CAN operator panel is shown
in Figure 18.

The NextMove ES CAN channel is opto-isolated, so a voltage in the range 12-24 V must be
applied to pin 5 of the CAN connector. From this supply, an internal voltage regulator provides
the 5 V required for the isolated CAN circuit. The required 12-24 V can be sourced from the
Baldor CAN I/O node or operator panel’s supply, which is internally connected to the CAN
connector as shown in Figure 20.
On Baldor CAN I/O nodes and operator panels, jumpers JP1 and JP2 must be set to position
‘1’ (the lower position) for the network to operate correctly. This configures the node’s CAN
channel to operate on pins 1 and 2 of the RJ45 connectors. On the Baldor CAN node, jumper
