Spare Part Overview & Technical Description
High-Voltage AC 60-110V Microstep Stepper Driver
The Yako YKA2811MA is an industrial heavy-duty microstep drive engineered to power large 2-phase hybrid stepper motors ranging from NEMA 34 (86mm) up to NEMA 51 (130mm) with phase currents up to 8.0A. Designed with a direct high-voltage AC 60V–110V power input stage, it eliminates the need for bulky DC switching power supplies, drawing power directly from a standard step-down transformer and maximizing high-speed motor torque.
Utilizing advanced bipolar constant-current wave chopping technology, the YKA2811MA delivers uniform constant-torque across 16 user-selectable microstep settings (up to 200 microsteps/step, equivalent to 40,000 pulses per motor revolution). An intelligent control loop suppresses motor vibration and eliminates acoustic stepping resonance across critical mid-band velocities. When the pulse signal ceases for 100ms, the driver automatically drops coil current to 20%–80% (configurable via DIP switch), keeping motor operating temperatures cool during machine idle states.
Key Engineering Highlights:
- High-Voltage Power Bus: Direct AC 60V-110V supply enables steep coil current rise times, sustaining high motor torque up to 1500 RPM.
- Resonance Suppressing Circuitry: Internal active damping eliminates mid-frequency stalling and harsh acoustic buzz.
- 16 Microstep Resolutions: Precision settings from 200 to 40,000 pulses per revolution accommodate both high-speed traversing and fine vector cuts.
- Optically Isolated I/O: 5V to 24V compatible logic inputs protect against industrial electrical noise and voltage spikes.
- Hardwired Protection Suite: Automatic shutdown on over-current, over-heat, and low line voltage conditions.
