CX and SX nuDrives
CF nuDrive Configuration
On CF nuDrives, the per-axis High-Speed Capture input signal is available
on pin 4 of each limit switch terminal block. Pin 5 provides an External
Inhibit input signal for remotely inhibiting the nuDrive axis. All limit
signals are filtered in the nuDrive and debounced by the FlexMotion-6C
controller to reduce noise sensitivity. The CF nuDrives and FlexMotion-6C
controllers provide for optically isolated limit switch inputs, and pin 6 is the
isolated (ISO) Common signal connection. Refer to Figure 10 for the CF
nuDrive terminal block pin assignments.

The Limit, High-Speed Capture, and External Inhibit signals are
opto-coupled inputs and require a voltage source. 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. Refer to the
I/O Terminal Blocks section of this guide for more
information on the FlexMotion-6C isolated input connection.
