AC Powered Stepper Drives

Two new AC powered STRAC drives from Applied Motion Products expand the offering to cover larger motors and applications where maximum power is required.

Operating on 90 to 240 AC, the drives eliminate the need for a DC power supply by internally converting input AC to the high DC bus voltages that enable larger step motors to be driven with maximum power. The STRAC2 provides up to 2.2 A/phase while the STRAC8 provides up to 8.0 A/phase; both feature advanced microstepping performance and sophisticated current control with anti-resonance. Anti-resonance electronically damps motor and system resonances, which improves smoothness of motion and torque over a wide speed range. Like the rest of the line, the drives can operate in step & direction or pulse/pulse control mode, selected by moving a jumper located under the cover of the drive. Each drive can microstep up to 20,000 steps/rev with a 1.8 º step motor (1/100 step), and can even microstep the step motor when the command pulses are low resolution, using a feature called Microstep Emulation. All drive setup is done via dip or rotary switches on the side of the drive, including motor selection, running current, idle current, and step resolution.
