Detailed Product Description

FOUR QUADRANTSCR DC DRIVE

MMT-115/230RT15AL

SCR series are full-wave positive feedback motor controllers and can control motors in It provides four-quadrant operation, which can torque in two speed directions.

  Features

1. Applicable to permanent-magnet, separate excitation DC motor

2. Large torque for low-speed start-up.

3. The mechanical characteristics of hardness, static error rate of 1%.

4. A wide speed-regulating range (0 - max).

5. A rapid dynamic response process.adjustable

6. Automatic and smooth transition process during acceleration or deceleration.

7. Current setting and current limiting protection (If the preset current value is exceeded, the driver stops output automatically.) 

8. Setting functions of and opposite soft start/soft stop time (adjustable)

9. Keyboard lock-up function.

10. Positive rotation and reverse rotation are selectable.

11. Dual closed loop PI adjustment (Current and Voltage)The closed-loop feedback is selectable.

12. The speed control mode and torque control mode are .
