With the operation of the feeder, the system weighs the material at each time unit and calculates the decreasing amount of material. This material amount is compared with the target value, and the motor is given a command for the calculated appropriate speed. Through simultaneous control and correction, the target value is maintained within a precise tolerance band.
- Control of 8 feeders can be done simultaneously.
- Material and output quantities can be directly controlled.
- It has high linearity.
- Interruptions in material feeding can be directly detected.
