The ENABLE switch is illuminated whenever it is switched on. It will not indicate that the
amplifiers/drivers are disabled under the following conditions: E-Stop (see the
section), Host Bus interlock fault, or amplifier/driver protection fault.
Conversely, it will not light if the external Enable function is used via the I/O terminal blocks.

SX nuDrives
When using an SX nuDrive, I/O pins 5 through 8 reflect the status of the
driver inhibits for axes 1 through 4 respectively. Each driver inhibit status
signal is the combination of the E-stop, enable, host bus interlock, and per
axis inhibit signals.
♦
CX nuDrives
To use the amplifier inhibit functionality of the 7344 controller, set jumpers
JP2 through JP5 to the Inhibit position (recommended). When the jumpers
are set to the Inhibit position, I/O lines 5 through 8 reflect the status of the
driver inhibits for axes 1 through 4 respectively. To use I/O lines
5 through 8 as general purpose digital I/O signals (required for
ValueMotion servo controllers), set jumpers JP2 through JP5 to the
Digital I/O position.
Note
Your CX nuDrive is shipped with jumpers JP2 through JP5 in the Digital I/O
position. These jumpers are located near the left edge of the interface board inside the
nuDrive, as shown in Figure 12.
