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 which current are below 8A. (Nema34=86mm, Nema51=130mm)

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

Typical Application:

• Mainly used in engraving machine, CNC machines, cnc routers, packaging equipment, polishing equipment, constant speed applications, laser cutting machine and textile equipment.
