    Connecting the NI 9512 The NI 9512 stepper drive interface module is part of a family of C Series motion modules. The module provides stepper drive interface signals for a single axis, a full set of motion I/O including...

  • Page 4: System Connection

    Working together they produce smoother motion resulting in precise stepper motion control. System Connection 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 power connection.
  • Page 5 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.
