Note:
Output current is automatically switched to 50% after signal pulse stop for about 0.4
seconds (according to the table settings). This can make the motor and drive heating reduction,
improved reliability. Theoretically 25% reduction in the heat (heat is proportional to the square of
the current).

Decay Mode Settings
With the decay mode from 0% to 100%, the attenuation increases. Users can eliminate the stepper
motor locked noise and improve motion stabilization by switch SW5, SW6.
