NI provides reliable, easy-to-connect motor drive solutions for NI embedded controllers in a variety of power ranges and form factors. NI embedded controllers also work with many third-party EtherCAT drives.
C Series Drives (NI 9502, NI 9503, NI 9505)
C Series drive modules integrate drive electronics directly into a CompactRIO chassis for a rugged, embedded motion solution. The LabVIEW SoftMotion Module is shipped with extensive ready-to-run examples for these modules and FPGA IP blocks for drive control components to get you up and running quickly. Drive control is implemented in LabVIEW FPGA allowing low-level customization of algorithms normally implemented in external drive firmware. All four modules are single axis. The NI 9505 is a full H-bridge module for driving brushed DC servo motors, relays, lamps, solenoids, and valves. The NI 9503 is a stepper motor drive and the NI 9502 is a brushless servo motor (BLDC or BLAC PMSM) drive.

C Series Drive Interfaces (NI 9512, NI 9514, NI 9516)
C Series drive interfaces for CompactRIO offer direct connectivity to hundreds of stepper and servo drives. These modules provide servo or stepper drive interface signals for a single axis. In addition, they offer a full set of motion I/O including inputs for a home switch and limit switches, incremental encoder inputs for position feedback, and digital input and digital output lines. The NI 951x drive interfaces include a processor to run the spline interpolation engine and the patented NI step generation algorithm or control loop.

Brushless Servo Drives
The AKD brushless servo drives feature cutting-edge technology for a single motion axis. They provide plug-and-play configuration with AKM brushless servo motors and connect to motion controllers either through an analog control signal or deterministic EtherCAT communication. From an NI real-time target with two Ethernet ports, you can implement motion systems that use EtherCAT communication to directly connect to EtherCAT drives. You also can take advantage of NI 9144 EtherCAT expansion chassis and C Series drive interface modules to connect to an AKD through analog control signals or step and direction commands. Because they are based on the same technology, local (analog control) and distributed (EtherCAT) motion axes can be combined within the same controller.

Stepper Motor Drives
SMD series stepper motor drives provide reliable, easy-to-connect cabling solutions for NI motion controllers. NI offers one-axis power drives with high-torque output, microstepping, and antiresonance control. The SMD-762x series AC input power drives offer 120/240 V bus and 5 A peak current output, and the SMD-761x series DC input power drives offer 12 to 75 V bus and 8 A peak current output. NI has direct connection solutions for connecting SMD drives to the NI 9512 C Series drive interface module or simply over Ethernet.
Third-Party EtherCAT Drives
The SoftMotion Drive Interface (SDI) allows plug-and-play integration of third-party EtherCAT motor drives with SoftMotion. Download and install SDI plug-ins for a variety of third-party drives from the LabVIEW Tools Network to get started on your motion application.
