3 NI 9512 Operating Instructions and Specifications
Caution
To meet radio frequency emission requirements for marine applications, use shielded cables and install the system in a metal enclosure. Suppression ferrites must be installed on power supply inputs near power entries to modules and controllers. Power supply and module cables must be separated on opposite sides of the enclosure and must enter and exit through opposing enclosure walls.
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 inputs for a home switch and limit switches, incremental encoder inputs for position feedback, 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.
NI 9512 Operating Instructions and Specifications 4 ni.com
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. Refer to Table 1 for the
DSUB connector pin assignments.
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. Refer to
Figure 2 for the MDR connector pin assignments.
Note
The NI 9512 requires an external power supply.
You can connect the external power supply to the V sup input provided on the DSUB or MDR connector. Do not connect more than one external power supply to the module.
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

Many stepper drive manufacturers offer opto-isolated inputs for
Step (CW)/Direction (CCW) signals. When connecting to opto-isolated inputs, configure the Step output type to single-ended, connect the NI 9512 Step+ output to the negative
(cathode) side of the optocoupler input, and leave the Step– output on the NI 9512 disconnected. Connect the positive (anode) side of the drive input to a supply as specified by the drive manufacturer.

The NI 9512 has four LEDs to display status information.
1 2 3 4
1 Axis Status (Green)
2 Encoder Active (Green)
3 Limit Active (Yellow)
4 Axis Fault (Red)
Axis Status
The Axis Status LED (green) has three states to display axis status.
• Off—The module is in sleep mode or failed to boot correctly.
Refer to the NI SoftMotion Module book of the LabVIEW Help for troubleshooting information.
• Flashing—The module booted up correctly and is functional.
• Lit—The module is functional and the drive enable output is active.
NI 9512 Operating Instructions and Specifications 20 ni.com
Encoder Active
The Encoder Active LED (green) has three states for encoder and
V sup
status.
• Off—The required power supply (V sup
) is not connected. You must connect a power supply to receive encoder pulses.
• Flashing—The power supply (V sup
) is connected and the module is receiving encoder pulses.
Note
The LED flash rate does not correspond to the rate at which the NI 9512 receives encoder pulses.
• Lit—The power supply (V sup
) is connected but the module is not receiving encoder pulses.
Limit Active
The Limit Active LED (yellow) has two states to display the status of the limits and home input.
• Off—The power supply (V sup
) is not connected, or both the limits and home input are not active.
• Lit—The power supply (V sup
) is connected and the forward limit, reverse limit, or home input is active.

21 NI 9512 Operating Instructions and Specifications
Axis Fault
The Axis Fault LED (red) has two states to indicate the presence of a fault in the system. Refer to the NI SoftMotion Module book of the LabVIEW Help for a list of module faults and troubleshooting information.
• Off—No module faults.
• Lit—One or more module faults.
Sleep Mode
This module supports a low-power sleep mode. Support for sleep mode at the system level depends on the chassis that the module is plugged into. Refer to the chassis manual for information about support for sleep mode. If the chassis supports sleep mode, refer to the software help for information about enabling sleep mode. Visit ni.com/info
and enter cseriesdoc
for information about
C Series documentation.
Typically, when a system is in sleep mode, you cannot communicate with the modules. In sleep mode, the system consumes minimal power and may dissipate less heat than it does in normal mode. Refer to the
information about power consumption and thermal dissipation.
