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)
List of modifications to functional parameters:
A:Modification of temperature protection value (change F_XXX to F_024, modify temperature protection value to 85 degrees)
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 F-000, press the "Shift" key once, and the last digit on the panel will flash. Press the "Add" key ▲ until F-004 appears. Press the "Shift" key again, and the second to last digit on the panel will flash. Press the "Add" key ▲ until F-024 appears. Press the "Function/Data" key FUNC/DATA once, and the panel will display 00800, indicating a protection temperature of 80 degrees. Press the "Shift" key twice on the keyboard, and the second to last digit display will flash. Press the "Add" key ▲ until 00850 appears. Press the "Function/Data" key FUNC/DATA once to set the protection temperature to 85 degrees.
B:Modification of low voltage undervoltage value (change F_XXX to F_022, modify low voltage protection value to 310V)
Explanation: The above inductance values are reference values, and the actual values are based on the operating current and display frequency.
Attention: When the coil is wound around the pipeline, the insulation cotton thickness should be higher than 20mm-25mm
Due to version changes, there may be slight adjustments. Please contact our technical staff
