We recommend wiring feedback as follows:
Resolver (attached to
motor from axis
module):
Connect to
feedback board:
Outputs A quad B to
CNC interface board:
1 (slot zero in AMP) FB0 CNC 1
2 (slot one in AMP) FB1 CNC 2
3 (slot two in AMP) FB2 CNC 3
4 (slot three in AMP) FB3 CNC 4
Connect your 9/Series CNC directly to the 1394 system module using
Allen Bradley cable 8520-DSC. This cable carries drive signals from the
9/Series CNC to the 1394 drive system. It also returns motor feedback to
the CNC from the resolvers (after it has been converted to A quad B on the
CNC interface board). Cable connections are made easily through the
bottom of the system module.
Connect this cable between the CNC interface board (connectors CNC1 to
CNC4) and either the 1394 digital 9/230 (connectors J1 to J3) or the four
axis 1394 digital servo card on the 9/260 or 9/290 (connectors J1 to J4).
