Terminal Introduction:

Symbol	Function	Specification
PWR	Power indicator	When power on, the green indicator lights up.
ALARM	Fault indicator	When over current, under voltage or over voltage, the red indicator lights up.
USB	Communication Interface	For software upgrade debugging and online applications
PU+	Pulse signal +	Connect with the signal power supply, 5V~24V can drive, need to connect a current limiting resistor with PU- when >5V
PU-	SW11=OFF, it’s pulse signal	Used to change motor direction. Input resistance 220Ω, requirements: low level 0~0.5V, high level 4~5V, pulse width >2.5us
	SW11=ON, it’s CW pulse signal
DR+	Direction signal +	Connect with the signal power supply, 5V~24V can drive, need to connect a current limiting resistor with DR- when >5V
DR-	SW11=OFF, it’s direction control signal	Used to change motor direction. Input resistance 220Ω, requirements: low level 0~0.5V, high level 4~5V
	SW11=ON, it’s CCW pulse signal	Effects on falling edge, the motor moves a step when the pulse goes from high to low. The input resistance is 220Ω. It requires: low level 0~0.5V, high level 4~5V, pulse width>2.5us.
MF+	Motor free signal +	Connect to 5V power supply, 5V~24V can drive, need to connect a current limiting resistor when volatge>5V
MF-	Motor free signal -	When effective (low level), the motor coil current is turned off, the driver stops working and the motor is free.
+V	Power supply +	DC20-50V
-V	Power supply -
AC,BC	Motor connection
