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.
| Subdivision (micro step) ppr | 400 | 500 | 600 | 800 | 1000 | 1200 | 2000 | 3000 |
| D5 | ON | ON | ON | ON | ON | ON | ON | ON |

| D7 | ON | ON | OFF | OFF | ON | ON | OFF | OFF |
| D8 | ON | OFF | ON | OFF | ON | OFF | ON | OFF |
| D9 | ON, double pulse: PU is positive pulse signal, DR is negative pulse signal | |||||||
| OFF, single pulse: PU is pulse signal, DR is direction signal | ||||||||
| D10 | Self detect switch (OFF: accept external pulse, ON: the driver send pulse to make the motor work at the speed of 30r/m) | |||||||
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
