1. Product features:
This motor controller is low voltage, four-quadrant regeneration and pulse-width modulation speed controlling system. The MCU (Microcontroller Unit) intelligent control makes quick response speed, smooth running, reliable operation and complete protections, etc.
PWM( pulse width modulation)
The PWM makes motor low noise, high efficiency and little maintenance. Service life of DC
motor can be further increased.
Four-quadrant regeneration in operating mode.
Regenerative braking function
External directional (or reversing) contactor is not required and components or parts of motor can be protected from superheating or burnout.
Enable/Brake/Reversing terminal
One of above functions can be achieved with help of passive switching value or open (or broken) circuit of transistor collector.
Status Light
Power light and various fault warning lights make the status of motor controller visible.
Speed value of Forward or Reverse can be set respectively.
Value of output current can be set.
Value of brake current can be set.
