YKA2811MA is identical-angle constant-torque microstep drive with working voltage AC60~110V. It’s designed for various models of two phase 86~130mm (NEMA 34~50) hybrid stepper motors which current are below 8A.
 
Features:
High performance, low noise with excellent stability and low cost
16 constant-torque microstep settings, 200 microsteps the highest
Unique control circuit, effectively reducing noise and increasing rotation smoothness
200Kpps response frequency
After step pulse stops for 100ms, output current change to 20%~80% (based STOP setting)
Bipolar constant current wave chopping mode, improve motor speed and power
Photoelectric isolated signal input/output
Drive current adjustable from 0.5A/phase to 8A/phase
Sole power input, voltage range: AC60~110V
Fault protection: over current, overheat, low voltage protection
Small size: 200*156*80mm, 2.3kg
 
Typical Application:
Mainly used in engraving machine, CNC machine, packaging equipment, polishing equipment, constant speed applications, laser cutting machine and textile equipment.
