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 |

D6 | ON | ON | ON | ON | OFF | OFF | OFF | OFF |
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
