ZLDBL5015 is a closed-loop speed controller. It adopts latest IGBT and MOS power device, and uses Hall signal of brushless DC motor to perform frequency multiplication and then performs closed-loop speed control. The control link is equipped with a PID speed regulator, and the system control is stable and reliable. Especially at low speed, the maximum torque can always be achieved, and the speed control range is 150~10000rpm.
FEATURES
■ PID speed and current double-loop regulator.
■ High performance and low price
■ 20KHZ chopper frequency
■ Electric braking function, make the motor respond quickly
■ The overload multiple is greater than 2, and the torque could always reach maximum value at low speed
■ With over-voltage, under-voltage, over-current, over-temperature, failed Hall signal and other fault alarm functions
■ Compatible with Hall and no Hall, automatic identification, no Hall sensing mode is suitable for special occasions (the starting load is relatively constant, and the starting is not very frequent, such as fans, pumps, polishing and other equipment,)
ELECTRICAL PARAMETERS
Standard input voltage: 24VDC~48VDC (10~60VDC).
Continuous output maximum current: 15A.
Acceleration time constant Factory default: 0.2 seconds.
Motor stall protection time is 3 seconds, others can be customized.
USING STEPS
1. Correctly connect the motor cable, Hall cable and power cable. Incorrect wiring may cause damage to the motor and driver.
2. When using an external potentiometer to adjust the speed, connect the moving point (middle interface) of the external potentiometer to SV port of driver, and other 2 interfaces are connected to the GND and +5V ports.
3.If an external potentiometer is used for speed regulation, adjust R-SV to the position of 1.0, at the same time connect EN to ground, connect the moving point (middle interface) of the external potentiometer to the SV port of the driver, and the other two to the GND and +5V ports .
4. Power on and run the motor, the motor is in the closed-loop maximum speed state at this time, adjust the attenuation potentiometer to the required speed.
