The STRAC8 stepper drive is an AC input digital step & direction drive, great for OEM applications requiring basic step & direction control of a 2-phase step motor. It accepts AC supply voltages from 90 to 240 volts. The STRAC8 outputs up to 8 A/phase to the step motor, and is compatible with a variety of 2-phase step motors that have been selected to optimize performance of both the drive and motor.

The STRAC8 drive features advanced microstepping performance and sophisticated current control with anti-resonance. Anti-resonance electronically damps motor and system resonances, which improves motor smoothness and torque over a wide speed range.

Each STRAC8 step motor drive operates in either Step & Direction or CW/CCW Pulse control mode. Selecting between these two modes is done by moving a jumper located under the cover of the drive. Each STRAC8 drive can microstep up to 20,000 steps/rev with a 1.8º step motor (1/100 step), and can even microstep the step motor when the command pulses are low resolution. This feature is called Microstep Emulation. All drive setup is done via dip switches on the side of the drive, including motor selection, running current, idle current, and step resolution.

This step motor drive is UL Recognized (E332730), CE approved, and RoHS compliant.
