MMT-115/230DR Series DC motor controller is a kind of speed governing product developed and produced by adopting past successful experience and combining modern advanced technology.

This dc motor speed controller have met international standard requirements and are sold to many countries. This pmdc motor speed control adopts thyristor chopping control principle and uses independent trigger mode. Even there is no velocity feedback, high speed ratio can be achieved to make it more accurate and reliable.

Excellent performance, reliable quality and high cost performance make it a strong performer in dc burshed motor speed control field and it was widely used in plastic machinery, food machinery, cable equipment, machining, paper printing, testing equipment, laboratory equipment and mixing equipment, welding equipment, electric soldering, electrowelding, electrical welding, welding positioner etc.

Internal potentiometer description

1. Soft starting time regulation: ACCEL
Regulate the ACCEL of such potentiometer can confirm that clockwise time of rising slop rises from initial speed to setting speed (i.e. rise time, setting time can be adjustable within 0.2-20s).

2. Soft stopping time regulation: DECEL
Regulate the DECEL of such potentiometer can confirm that clockwise time of descending slop declines from maximum speed to minimum speed (i.e. fall time, setting time can be adjustable within 0.2-10s).

3. Maximum speed limit: MAX SPD
Turn the given potentiometer up to maximum value, and then regulate MAX SPD potentiometer to limit the maximum output revolving speed, clockwise rotate to increase output voltage.  

4. Minimum speed limit: MIN SPD
Turn the given potentiometer up to minimum value, and then regulate MIN SPD potentiometer to limit the minimum output revolving speed, clockwise rotate to increase output voltage.  

5. Current limit regulation: TORQUE
Regulate such potentiometer can limit the maximum output current of driver board, according to motor`s rated current settings selected, maximum output current of driver board shall be 120%-200% of motor`s rated current. Clockwise rotate to increase current.

6. Torque compensation regulation: IR COMP
Regulate IR COMP potentiometer to operate the motor under different loads and keep it revolving speed constant, clockwise rotate to increase torque.
