Danfoss inverter intelligent logic counter function

Introduction: Many small production machines are required to count the output of the product. When the output meter reaches a certain preset value, it will stop automatically; when restarting, the counter will be manually reset and then turned on, so the output will start to count again until the preset value. . Previously the counter function usually relied on external counters to complete. Danfoss FC series inverter built-in powerful SLC logic control function, through the logic program, can realize the counter control function.

First, counter control function requirements:

Figure 1 is a picture of an ordinary industrial counter. The general counter has a digital signal input and a digital signal output. The current count value and the preset value are displayed on the panel. The preset value can be set by the user.

Figure I. Ordinary industrial counter

The working sequence diagram of the counter is shown in Fig. 2. When the product quantity count reaches the preset value, the counter digital output signal acts to stop the host from running. After the user resets the counter, the host can run again.

Second, Danfoss FC series inverter intelligent logic function description:

The built-in intelligent logic function of Danfoss FC series inverter is Danfoss PLC logic control function which is open to the user. Users can customize the special program according to their actual needs. Danfoss has specially developed MCT10 software for user-friendly programming. The logic logic programming method is shown in Figure 3.

Figure 3, smart logic programming diagram

The main logic trigger conditions are the following:

1. Digital input and output;

2. Comparator output

3. Logical rules output;

4. Timer output;

5. State of operation, stop, warning and alarm;

6. Frequency, current reaches a predetermined value;

......

Smart logic execution actions mainly include the following:

1. Select menu, preset frequency or acceleration time;

2. Control start, stop and other inverter actions;

3. Start timer

4. Control digital output;

......

Third, the intelligent logic function to achieve the counter control function solution:

The specific wiring diagram is shown in Figure 4.

See Figure 3 for the program.

Parameter settings slightly.

Concluding remarks: Danfoss' new FC series inverters have built-in powerful intelligent logic control functions. The counter function can be realized through simple programming. At present, this solution has been used at a pager equipment supplier, and the function fully meets customer requirements. The original scheme is more streamlined and less expensive than the system.

Benefits of smart rice cooker - what are the advantages of smart rice cooker?

1. Intelligent rice cooker uses three-dimensional heating, original ceramic crystal inner tank far-infrared heating, super wear-resistant, non stick pot, spherical bottom inner tank, home spherical heating plate, more uniform heating, original micro pressure technology, full and elastic rice particles, non stick and non stick, imitating the principle of open fire as rice, 6-stage only fire, more accurate, removable inner cover, more convenient cleaning.

2. The intelligent rice cooker is controlled by computer chip program, monitors the temperature in real time, flexibly adjusts the fire power, and automatically completes the cooking process. It has three advantages of "delicious cooking, regular appointment and multiple functions".

3. The shape difference between the intelligent rice cooker and the Electric Rice Cooker is that the electric rice cooker and the cover are connected, which is conducive to heat preservation, while the electric rice cooker is separated from the pot and cover. In terms of use, the electric rice cooker can cook food and rice, and the electric rice cooker can also steam cake or soup in addition.

4. Compared with the electric rice cooker, the electric rice cooker can be said to be an extension of it. The new electric rice cooker has undergone great changes in structure, function and control mode, from the ordinary type with exposed inner pot to the luxury all inclusive type; From the single function of cooking to porridge, soup and cake steaming; The control mode has also developed from simple mechanical control to computer control, fuzzy control and so on; The appeal point of publicity has also developed from the original convenience to make rice healthier, more nutritious and sweeter.
