Baldor Can - Baldor NextMove ESB-2 Installation Manual

4.5.4 Baldor CAN

The NextMove ESB-2 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:
InputNode 8 (Baldor part ION001-503) - an 8 x digital input CAN node.

OutputNode 8 (Baldor part ION003-503) - an 8 x digital output CAN node.

RelayNode 8 (Baldor part ION002-503) - an 8 x relay CAN node.

IoNode 24/24 (Baldor part ION004-503) - a 24 x digital input and 24 x digital output CAN

node.
KeypadNode (Baldor part KPD002-501, obsolete) - an operator panel CAN node with a

4 x 20 LCD display and 27 key membrane labeled for control of 3 axes (X, Y, Z).
KeypadNode 4 (Baldor part KPD002-505, obsolete) - an operator panel CAN node with a

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 ESB-2 and a Baldor CAN operator panel is
shown in Figure 29.

The NextMove ESB-2 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 29.
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
JP3 can be used to connect an internal 120 Ω terminating resistor, provided the node is at
the end of the network. Jumpers JP4 and JP5 can be used to configure the node ID and
baud rate.
Up to 63 Baldor I/O nodes (including no more than 4 operator panels) can be added to the
network by the NextMove ESB-2 using the Mint NODETYPE keyword. Any network and node
related events can then be monitored using the Mint BUS2 event.
