CURRENT SETTING

Stepper driver working current is set by DIP switches D1 to D4.

SUBDIVISION (MICRO STEP) SETTING

The subdivision (micro step) is set by DIP switches D5 to D8, 16 channels in total. D9 and D10 are used to set the driver function.

I/O SIGNAL

All of the input signals are opto-isolated. To ensure the built-in high speed optocoupler effective, the drive capacity of current for control signal must be 15mA or more. Because of internal optocoupler current-limiting resistor, if input signal voltage of stepper driver is above 5V, please use external resistor R to limit current.

When input signal voltage is:

+5V: R1=0, R2=0;

+12V: R1=510Ω, R2=820Ω;

+24V: R1=1.2KΩ, R2=1.8KΩ
