l  32 bit DSP control technology, low noise/vibration with excellent stability and low cost

l  16 constant-torque microstep settings, 200 microsteps the highest

l  Smooth and accurate current control, effectively reduce motor heats

l  200Kpps pulse response frequency

l  After step pulse stops for 200ms, output current automatically halve to reduce motor heat

l  Excellent smoothness in low frequency high microstep applications

l  Photoelectric isolated signal input/output, high anti-interference ability

l  Drive current adjustable (under 4A)

l  Input voltage range: DC20~80V

l  Fault protection: over current, over voltage, low voltage protection, etc.

l  Small size: 118*76*33mm, 0.3kg

Typical Application:
Mainly used in medical equipment, dispensing machines, engraving machine, laser equipment, labeling machines, electronic equipment, advertising equipment and other automation equipments. Works particularly good in the expectations of low heat, small noise

YKD2405M/YKD2408M is high performance digital step drive based on YAKO’s new 32-bit DSP technology. It’s designed for various models of two phase 42~86mm (NEMA 17~34) hybrid stepper motors which current are below 4A.

With servo-similar control circuit and superior software algorithm, YKD2405M/YKD2408M has superior performance in smoothness, noise and vibration. Smooth and accurate current control technology greatly reduces motor heat.
