Stepper Drives output 0.5-6.0 A with 90-135 Vac input.

Press Release Summary:

Providing software selectable resolutions from 200-51,200 steps/rev at speeds up to 133 rps, Series STAC6 includes self-test and auto setup features that measure and configure motor parameters. Demand signal smoothing minimizes extraneous system resonances, while torque ripple smoothing adjusts current waveform to reduce low speed torque ripple. Control options include intuitive graphical programming language as well as high-level language.

Original Press Release:

Features-Laden Stepper Drives Obtain Maximum Performance from Today's Stepper Motors

WATSONVILLE, CA - Applied Motion Products introduces the STAC6 High Performance Stepper Drive. These drives offer advanced features to provide absolute maximum performance benefits from a stepper motor. They feature current output from 0.5 to 6.0 A with 90-135 VAC input, 50/60 Hz, and provide software selectable resolutions from 200 to 51,200 steps/rev at speeds up to 133 rps.

Self-Test and Auto Setup features measure and configure motor parameters automatically, while anti-resonance technology eliminates midrange instability for higher motor speeds and fuller use of available torque. Demand Signal Smoothing reduces extraneous system resonances for smoother motor performance and reduced wear on mechanical components. Torque Ripple Smoothing adjusts the current waveform to reduce low speed torque ripple for smooth motion at low motor speeds. Additionally, MicroStep Emulation provides smooth motion for systems that require low step resolutions, such as retrofit systems with controller resolution that is fixed at a low value and cannot easily be changed.

Two integral control options are available, including an intuitive graphical programming language as well as a comprehensive high-level language for precise control of all drive features. Setup and configuration is also made easy with graphical, intuitive CONFIGURATOR software. The drive can be configured from a drop-down menu, or the user can quickly create custom motor configurations if desired.

In applications requiring an encoder, the STAC6 offers additional benefits. These include Stall Detect that can trigger a fault output when a motor has not reached its programmed position, Position Maintenance to hold the motor position firm even when external forces are trying to move it out of position, and Stall Prevention where the drive will work to end the desired move with new parameters.

Founded in 1978, Applied Motion Products specializes in cost-effective, high precision motors and motion control solutions. They offer a full complement of stepper and Brushless servo motors, positioning control electronics and gearheads to industrial and OEM customers.
