The control driver is a closed-loop speed controller. It adopts the latest IGBT and MOS power devices. It uses the Hall signal of the 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.
Two product features:
1. PID speed and current double-loop regulator
2. High performance and low price
3. 20KHZ chopper frequency
4. Electric braking function, make the motor respond quickly
5. The overload multiple is greater than 2, and the torque can always reach the maximum at low speed
6. With overvoltage, undervoltage, overcurrent, overtemperature, illegal Hall signal and other fault alarm functions
Three electrical indicators
Standard input voltage: 24VDC, the minimum voltage is not less than 8VDC, and the maximum voltage is not more than 30VDC.
Continuous output current: 5A
Acceleration time constant Factory default: 0.2 seconds Others can be customized
3. Control signal part:
GND: signal ground
F/R: Forward and reverse control, connect to GND for reverse, not to forward, when switching between forward and reverse, turn off EN first
EN: Enable control: EN is grounded, the motor turns (online state), EN is not connected, the motor does not turn (offline state)
SV: External speed attenuation: It can be attenuated from 0 to 100%. When the external speed command is connected to 5V, the speed can be adjusted through this potentiometer
+5V: Speed regulation voltage output, which can be continuously adjusted by potentiometer between SV and GND
Built-in potentiometer (driver PCB board): Adjust the motor speed gain, which can be adjusted from 0 to 100%.
