4.2 Current Settings
Output current is set by SW3, 24of the DIP switch as shown in the following table:
SW3 SW4
Full Current Auto Half Current
Peak Current RMS Peak Current RMS
OFF OFF 3A 2.14A 1.5A 1.07A
ON OFF 2.25A 1.6A 0.6A 0.42A
OFF ON 1.5A 1.07A 1.5A 1.07A
ON ON 0.6A 0.42A 0.6A 0.42A
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).
4.3 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.
SW5 SW6 Decay Mode
OFF OFF No Decay
ON OFF Slow Decay
OFF ON Medium Speed Decay
ON ON Fast Decay
