Signal Connections

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. Figure 3-3 shows a single-ended
connection example.

Figure 3-3.

Opto-Isolated Step and Direction Output Connection

Caution

If the optocoupler input does not include its own current-limiting resistor,

you must provide an external resistor in series with the NI 9512 output. To prevent
damage to the NI 9512 drive interface module or stepper drive, use a resistor that
limits the current to a value below the maximum specifications of the drive interface
module and stepper drive. Refer to Appendix A,

Specifications

information.

Note

Refer to Appendix B,

Position Command Connections

, for position

command signal descriptions and information about connecting the NI 9512 module
to drives that support position command mode.

Servo Command Signals

Drive Command Output

The Drive Command output on the servo drive interface modules provide a ±10 V analog output.
The Drive Command output features software configurable torque limits and voltage offset.

Drive Command COM

To help keep digital noise separate from the analog output, there is a separate return connection.
Use this reference connection as the reference for the Drive Command output when connecting
to servo drives instead of using COM (digital I/O reference).

Additional Drive Signals

Drive Enable

Use the Drive Enable output on the NI 951x module to control the enable function of a drive.
The enable input on the drive must be active for the drive to acknowledge commands from the
module. The Drive Enable signal is active during normal operation and deactivated upon a fault
