The NI 9512 C Series stepper drive interface modules provides stepper 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 (optional), and 0 to 30 V digital input and output lines. The NI 9512 also includes a processor to run the spline interpolation engine and patented NI step generation algorithm. Working together, they produce smoother motion resulting in precise stepper motion control.
The NI 9512 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 stepper drives, 0 to 30 V general-purpose digital input and output lines, and a +19 to 30 V input for C Series module power connection. The 20-pin MDR connector includes 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 9512 to stepper drives. You can use the NI 9512-to-P7000 Stepper Drives Connectivity Bundle to connect the NI 9512 to the P70530 or P70360 stepper drives from NI. To connect to third-party stepper drives, you can use the NI 951x Cable and Terminal Block Bundle.
