DSP chip digital signal processor

Brief Description of Induction Heating TMS320F2810 DSP Chip

Digital signal processor (DSP) chips have been widely used in communication, automatic control, aerospace, military, medical and other fields.

The TMS320F2810 DSP chip has the following main features:

(1) Can complete one multiplication and one addition within one instruction cycle;

(2) The program and data space are separated, allowing for simultaneous access to instructions and data;

(3) The chip has fast RAM, which can usually be accessed simultaneously in two RAM blocks through independent data buses;

(4) Hardware support with low or no overhead loops and jumps;

(5) Fast interrupt handling and hardware I/O support;

(6) Having multiple hardware address generators that operate within a single cycle;

(7) Can perform multiple operations in parallel;

(8) Support pipeline operations, allowing for overlapping operations such as finger retrieval, decoding, and execution.

The superiority of digital signal processing systems is demonstrated by:

1: Good flexibility: When there are changes in processing methods and parameters, only the software design needs to be modified to adapt to the corresponding changes;

2: High accuracy: The signal processing system can meet the accuracy requirements through the number of bits of A/D conversion, the word length of the processor, and appropriate algorithms;

3: Good reliability: The system is less affected by environmental temperature, humidity, noise, and electromagnetic interference;

4: Large scale integration: With the development of semiconductor integrated circuit technology, the integration degree of digital circuits can be made very high, with advantages such as small size, low power consumption, and good product consistency.

Operation panel instructions

Function description of buttons and indicator lights

The status monitoring mode is the working mode of the operating keyboard in most cases. In any case, as long as there is no key input for 1 minute continuously, the operating keyboard will automatically return to the status monitoring mode.

Operation mode and display status of keyboard

The keyboard can be divided into 5 working modes based on the displayed content and received instructions:
1. Status monitoring mode (30.303)
2. Monitoring parameter viewing mode (D-XXX): In this mode, press the ▲/▼ keys to select the state that needs to be monitored.
3. Function parameter viewing and modification mode (F-XXX): In this mode, press the ▲/▼ keys or use the SH IFT key to select the function parameters that need to be viewed or modified.
4. Function parameters to be modified mode.
5. The mode for modifying the frequency setting of numbers can only be activated when controlling heating with the up and down keys on the keyboard panel.

Use of keyboard operation

Viewing display of monitoring parameters:
1. Monitor the working DC voltage (change D_XXX to D_230 to view the working DC voltage). Press the "PRG" button to select a working mode between "Monitoring Parameter Viewing Mode" and "Functional Parameter Viewing and Modifying Mode". When the keyboard displays D-232, press the "decrease key ▼" until D-230 appears, press the "function/data key FUNC/D ATA" on the keyboard, and the panel will display the DC operating voltage: 540V. (This value may vary depending on the input voltage)

2Monitor the working temperature (change D_XXX to D_231 to view the working radiator temperature), press the "PRG" key to select a working mode between "Monitoring Parameter Viewing Mode" and "Functional Parameter Viewing and Modifying Mode". When the keyboard displays D-232, press the "decrease key ▼" until D-231 appears, press the "function/data key FUNC/DATA" on the keyboard, and the panel displays the working heat sink temperature: 62.6 degrees. (This temperature value may vary in different work sites)

When the keyboard displays F-000, press the "Shift" key once, and the last digit on the panel will flash. Press the "Increment" key ▲ until F-002 appears. Press the "Shift" key again, and the second to last digit on the panel will flash. Press the "Increment" key ▲ until F-022 appears. Press the "Function/Data" key FUNC/DATA, and the panel will display 00350. The protection voltage value is 350V. Press the "Shift" key twice on the keyboard, and the second to last digit will flash. Press the "Increment" key ▲ until 00310 appears, and then press the "Function/Data" key FUNC/DATA. If/DATA is used once, the protection voltage is set to 310V.

After correctly wiring and powering on the variable frequency induction heater, please check the following parameters:

Is the working voltage normal? It is generally 540V when input at 380VAC;

Is the temperature of the radiator normal? When the radiator is powered on and not working, it is generally close to the working environment temperature; Is the indicator light on the variable frequency induction heater panel normal and is the fault indicator light on;

If any of the above abnormal situations occur, please refer to the specific functional instructions in this manual for adjustments or seek services.
