NI 9514

C Series Servo Drive Interface with Encoder Feedback

Configure Page for: Print PDF Rich Text
  • 50 μs control loop rate
  • Onboard spline interpolation and advanced features like position capture and position compare
  • Torque and position mode control
  • Forward limit, reverse limit, home switch, and general-purpose digital inputs
  • Encoder input
  • Terminal Block connectivity to third-party servo drives


The NI 9514 C Series servo drive interface module provides servo drive interface signals for a single axis, a full set of motion I/O including inputs for a home switch and limit switches, incremental encoder inputs for position feedback, and 0 to 30 V digital input lines. The NI 9514 also includes a processor to run the spline interpolation engine and proportional integral derivative (PID) control loop. Working together, the processor and PID control loop produce smoother motion resulting in precise servo motion control.

The NI 9514 has two connectors: a 15-pin DSUB drive interface connector and a 20-pin MDR feedback connector. The 15-pin DSUB includes command signals for interfacing with servo amplifiers or drives, a 0 to 30 V general-purpose digital input line, and a +19 to 30 V input for power connection. The 20-pin MDR connector features incremental encoder feedback inputs, a +5 V output for encoder power, home, limit, and position compare inputs; an output for position compare; an additional +19 to 30 V input for power connection; and an additional 0 to 30 V general-purpose digital input line.

National Instruments offers several options for connecting the NI 9514 to servo drives. You can use the NI 951x Cable and Terminal Block Bundle to connect to third-party servo drives.

The chassis provides rugged, modular housing for the controller and modules and contains the high-performance CompactRIO backplane, which includes the system's data, timing, triggering buses, and field-programmable gate array (FPGA) chips.
The embedded controller runs your application and interfaces with your CompactRIO modules.
This device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware). LabVIEW and the LabVIEW FPGA Module deliver graphical development for field-programmable gate array (FPGA) chips on NI reconfigurable I/O (RIO) hardware targets.
