DAC Outputs

NI-Motion Functions

DAC Outputs

DAC resources are typically mapped to servo axes and generate the analog control outputs from the PID loops. DAC resources that are not used by axes are available for non-axis specific applications. You can directly control an unmapped DAC as a general-purpose analog output.

The DAC outputs offer 16-bit resolution and the industry-standard ±10 V range. Refer to the specifications of the motion controller documentation for complete DAC output specifications. The following table lists the resource IDs and constants for DACs:
