Connectivity Options
The controller connector on the MCA-7724 Motion Axis Router connects
to the 68-pin motion I/O connector on your controller. The adapter then
reroutes signals from the motion I/O connector to the accessory connectors
on the MCA-7724 Motion Axis Router. You can connect motion drives and
accessories in a 2 + 2 connectivity option or a 3 + 1 connectivity option.
Figures 2 and 3 show the two connectivity options.
Caution Connect motion drives and accessories only to connectors A and B (2 + 2
connectivity option) or to connectors C and D (3 + 1 connectivity option). Failure to
connect the motion drives and accessories as shown in Figures 2 and 3 may result in
damage to the motion controller, axis router, drive, or accessory.
2 + 2 Connectivity Option
Controller axes 1 and 2 from the controller correspond to axes 1 and 2 on
connector A, and controller axes 3 and 4 correspond to axes 1 and 2 on
connector B, as shown in Figure 2.
