NI 9501 C Series Stepper Drive

Starting at $ 567 (view pricing options)
  • 3 A RMS (4.24 A peak) current per phase
  • Advanced PWM algorithm reduces torque ripple, minimizes power loss, and smoothes microstepping
  • Software-programmable full-step, half-step, and microstepping rates up to 256
  • Direct connectivity to 2-phase bipolar or unipolar hybrid stepper motors
  • Software-programmable current reduction for reduced power consumption
  • Create powerful custom motion control systems using the LabVIEW NI SoftMotion Module
  • Configure Complete CompactRIO System
The NI 9501 is a C Series stepper motor drive for the NI CompactRIO platform. It adds integrated stepper motion abilities to a CompactRIO system without the need for an external power drive or connector block.

The NI 9501 benefits electronics engineers designing consumer appliances, industrial control engineers designing small- to medium-sized machines, and automotive engineers working on rapid prototyping applications by providing seamless motion integration with a proven measurement and control platform. With more than 100 NI and third-party C Series I/O modules to choose from, the CompactRIO platform offers a powerful option for integrating multiple measurement types, machine vision, and motion in one system, all powered by NI LabVIEW software.

For more information on compatible NI reconfigurable I/O (RIO) hardware platforms, stepper motors, and the benefits of stepper motor control with the LabVIEW NI SoftMotion Module, see the data sheet and the Resources tab.
