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.
