Summary

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
proportions, etc.
PWM( pulse width modulation)
The PWM makes motor low noise, high efficiency and little maintenance. Service life of
DC motor can be fatherly 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 superheated 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.
Keyaa MMTdc Motor Controller User’’ss Manual
Speed value of Forward or Reverse can be set respectively.
Value of output current can be set.
Value of brake current can be set.
Torque compensation
Double closed loop PI regulation(Voltage and current)
Standard analog signal
Analog quantity (0-5V) or potentiometers are suitable for controlling.
Overvoltage or under voltage protection
Overheating protection
When temperature is overtop, motor controller will reduce output current to prevent
from superheated with help of decision circuit .if the temperature is still overtop, the
controller will stop output and protect motor and motor controller.
