Overview

Product overview

Key product information and technical features.

The NI-9516 connects a CompactRIO motion-control system to an external servo drive. NI documents an analog ±10 V interface and an NI 9514/16-to-AKD cable option for supported AKD drive configurations.

For NI 951x systems using SoftMotion and the RIO Scan Engine, control loops, encoder settings, and drive signals are configured in the LabVIEW project without requiring FPGA programming.

  • Dual encoder feedback for a single servo axis.
  • Home-switch, limit-switch, and digital inputs.
  • Onboard spline interpolation and PID control.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the NI-9516 directly power a servo motor?

No. It provides a drive interface; an external servo drive supplies motor power.

How does the NI-9516 differ from the NI-9514?

Both are single-axis servo interface modules. The NI-9516 has dual encoder inputs, while the NI-9514 has a single encoder input.
