Quartet Electric C320 Inverter in Kaiping Machine (Figure)

1, Summary With the market for security doors and the large demand for leisure products in recent years, the rise of the cold-rolled plate as raw materials, the production efficiency of Kaiping and production process put forward higher requirements. The following is the use of a security door company in Shenzhen City Quartet Electric Limited production of the C320 Inverter A Kaiping machine crude whole drive controller case.

2, Process Description: Kaiping machine is divided into two full roll process: first the whole roll for the rough, finishing second to roll, after the middle of a buffer pit. Raw materials arrive at the table, the knife cut through the hydraulic Shearing. The whole system process as below:

Figure 1, Kaiping machine flow chart

3, electrical components: System using coarse whole part of the four C320-free Sensor Vector Inverter , Some use the finishing precision positioning servo, Mitsubishi FX2N Series PLC And HMI Composition parameter setting and operation control systems.

1, the entire system through the user interface to set the product size, speed and other parameters.

2, through the photoelectric sensor signal sampling Mitsubishi PLC, Inverter control the whole of the rough.

3, finishing servo part of the set directly through the user interface.

4, crude whole electrical part of production using the four-C320-4T0110 series inverter.

C320 series sensorless vector inverter, sensorless control with unique technology, wide voltage design, low-frequency high output torque, can meet production requirements process.

4, control theory: Raw material arrives after the entire buffer through the rough pit, after finishing the buffer after the pit to the exact size by product set Length to the table, and then fall into the hydraulic chopper Zhanxia automatic blanking units. The whole part of the rough track to the pit to the location to adjust the speed of raw materials, product size and speed to set directly on the touch screen. Considering the cost, frequency converter by the PLC with multi speed control, installed in the ground pit by four photoelectric sensors to detect the location of raw materials, then position signal sent to the PLC, the PLC controls the speed transducer. Material position feedback transducer in position 1 high-speed operation, in position 2 in the speed run, speed run in position 3, position 4 in the frequency converter stops running. In the actual production line speed because of the thickness of raw materials and product size varies, so requires a very good converter performance acceleration and deceleration to speed up the production line.

5, C320 inverter parameter settings: F0.0: 1 No sense of vector control

F0.1: 9 external Terminal Select

F0.4: 0001 start using the external terminal control inverter

F0.10: 3 Acceleration time 3 seconds

F0.11: 2 deceleration time 2 seconds

F1.15: 380 F1.16: 50 F1.17: 21.5 F1.18: 1460 set Motor Rated parameters

F3.0: 1 F3.1: 2 F3.2: 3 multi-speed external terminal functional definition

F5.1: 45 multi-speed frequency 1

F5.2: 25 multi-speed frequency 2

F5.4: 10 multi-speed frequency 3

6, concluded:

Results show that after debugging, use the C320 inverter control system composed of Kaiping, to overcome the electronic control system in the original packing materials, causing scratches and other problems in the pit, fully meet the production process and the frequent acceleration and deceleration torque site requirements often change.

Motion Detection - what is the best sensor, when the view is blocked?

A photoelectric sensor won't work as the person is blocked from view of the sensor. Can i use ultrasonic or some other sensor to notice that someone has entered the room?

Maybe magnetic type could also be used.

You could also use thermal imaging sensor.
