CF nuDrive Configuration
There are two I/O connectors (upper and lower) on the CF nuDrive. Each
I/O connector uses a six-position removable screw terminal block. The
upper terminal block provides access to four channels of ±10 V A/D
converter analog input as well as analog reference voltage output from the
converter circuit and reference common signal connections. The lower
terminal block provides access to breakpoint output digital I/O signals as
well as an isolated external power supply voltage input connection. Refer
to Figures 14 and 15 for the upper and lower FlexMotion-compatible I/O
terminal block pin assignments.

The breakpoint output digital signals are opto-coupled outputs and require
an isolated voltage source connected to the isolated voltage and isolated
common inputs. You can either use an external isolated voltage source, or
you can use the +5 V and ground signals on the host computer by properly
setting a jumper to connect the isolated voltage (input) to 5 V and the ISO
Common signal on the FlexMotion-6C board. Refer to the FlexMotion-6C
Hardware User Manual for more information.
