Functions | Operation Instructions | |
PWR | Power Indicating Lamp | When the driver is powered on, the green light is always on. |
ALARM | Overcurrent/Undervoltage Indicator | When the overvoltage and overcurrent faults occur, the red light is always on. |
PUL+ | Positive End of Control Pulse Signal | Connect to signal power,+5V to +24V can be driven. |
PUL- | Negative End of Control Pulse Signal | The falling edge is valid, and the motor takes one step whenever the pulse changes from high to low. Input resistance 220Ω. Requirements: low level 0 to 0.5V, high level 4 to 5V, Pulse charge >2.5us. |
DIR+ | Positive End of Directional Signal | Connect to signal power,+5V to +24V can be driven. |
DIR- | Negative End of Directional Signal | Used to change the direction of the motor. Input resistance 220Ω. Requirements: low level 0 to 0.5V, high level 4 to 5V, Pulse charge >2.5us. |
ENA+ | Positive End of Enabling Signal | Connect to signal power,+5V to +24V can be driven. |
ENA- | Negative End of Enabling Signal | When it is valid (low level), the motor coil current is turned off, the driver stops working, and the motor is in a free state. |
ALM+ | Positive End of Alarm Signal Output | When over-current, over-voltage, under-voltage or over-tolerance alarms, the alarm signal is valid (the output photocoupler is turned on). ALM+ is connected to the pull-up power to use the positive pole of the output power supply, and ALM- is connected to the negative pole of the output power supply. Maximum drive current 50mA. |

Tips: What is a stepper motor driver?
Stepper motor driver is mainly composed of ring distributor, push stage, protection circuit and sensor. The function of the circular distributor is to generate the switching waveform signal processing of the motor in different states according to the requirements of the input signal. The driving stage is to amplify the voltage and current of the switching signal to enhance the main switching circuit. The protection circuit is responsible for generating a shutdown signal to shut off the main circuit when the winding current is too large to protect the motor driver and motor windings. The sensor is responsible for real-time monitoring of the position and angle of the motor, and the generating device for returning the signal the role of.
