OMEGA Engineering, Inc. Step and Direction Stepper Drives STR

The STR series stepper drive is a compact, powerful, digital step and direction drive available in two power ranges: 4 A/phase and 8 A/phase. The STR series is ideal for applications requiring basic step and direction control of a 2-phase step motor. STR drives feature 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. All setup is done via dip switches and a rotary switch on the side of the drive, including motor selection, running current, idle current, and step resolution.STR drives are available with a large family of compatible 2-phase step motors, selected to optimize performance of both the drive and motor.
