[DANFOSS] Pacific Scientific 6410 Stepper Driver

2026-04-09

In the field of industrial automation, stepper motor drivers play a crucial role in converting pulse commands into motor winding currents. The 6410 two-phase bipolar stepper driver launched by Pacific Scientific is designed for applications that require high resolution, smooth motion, and stable operation over a wide speed range. This driver converts step and directional inputs into motor winding currents and integrates multiple patented technologies, including four phase PWM chopper regulation, digital electronic damping, and flexible micro step selection. Its output current can be selected in 8 levels between 0.625A RMS and 5A RMS through a dip switch, with a supply voltage range of 24 to 75V DC. It is compatible with Pacific Science Company's standard and high-performance series hybrid stepper motors, as well as most other brands of two-phase stepper motors.
