Inhibit Output Settings

Inhibit outputs are typically connected to the Drive Enable signal on the servo or stepper drive to control the enable/inhibit function of the drive. This signal is used to disable the servo amplifier or stepper driver for power savings, safety, or other specific application reasons. You also can use inhibit outputs as general-purpose outputs.

When enabled, a per-axis inhibit output is linked to the motor off state of the corresponding axis. A killed axis (motor off) forces the corresponding inhibit output on. When the axis is active, the inhibit output is off.

Note  Totem Pole configuration for inhibit outputs is only available on NI 7350 controllers. Totem pole configures the inhibit output to sink and source current. Refer to the NI 7350 Hardware User Manual for more information. The output mode is not configurable on NI 7330/40/90 motion controllers.
