This product has three working modes: speed control, current control, and open-loop control. It can realize control functions such as braking, direction, prohibition, maximum current limit setting, one-stage amplification, two speed settings, etc.; there are also auxiliary functions such as external potentiometer, internal potentiometer, external analog, external PWM/pulse signal, and acceleration ramp delay function, as well as overload protection, overheating protection, blockage protection, etc.; various functions are easy to operate; high speed control, the maximum speed of a pair of poles motor can reach For details, please refer to the related content.
