Over Current: light on continuing
Over Voltage: light fast blink
Over Heat: light slow blink
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 no less than 15mA. Because of internal optocoupler current-limiting resistor, when input signal voltage of stepper driver is above 5V, please use external resistor R to limit current.
When input signal voltage is:
+5V, then R1=0, R2=0;
+12V, then R1=510Ω, R2=820Ω;
+24V, then R1=1.2KΩ, R2=1.8KΩ
