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.
PU+	Pulse signal +	Connect with the signal power supply, +5V~+24V can drive, need to connect a current limiting resistor with PU- when >+24V
PU-	Pulse signal -	The motor starts running whenever the level changes from high to low. Requirements: low level 0~0.5V, high level 5~24V, pulse width >2.5us
DR+	Direction signal +	Connect with the signal power supply, +5V~+24V  can drive, need to connect a current limiting resistor with DR- when >+24V
DR-	Direction signal -	Used to change motor direction. Requirements: low level 0~0.5V, high level 5~24V， 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>24V
MF-	Motor free signal -	When effective (low level), the motor coil current is turned off, the driver stops working and the motor is free.
ALM+	Alarm output signal +	The alarm signal is valid when overcurrent, overvoltage, undervoltage or out of tolerance alarms. ALM+ is connected to the pull-up resistor to the positive terminal of the output power supply, and the ALM- is connected to the negative terminal of the output power supply.
ALM-	Alarm output signal -
