DSP CONTROL INDUCTRION HEATING MACHINE DESCRIPTON :
1. Built-in process temperature PID closed loop program (optional), PID parameters can be set:
1) In many cases, the constant temperature operation mode can be used to automatically control the heating temperature of the workpiece and the output power of the power supply. After the temperature reaches the set value, the temperature is kept constant. Process PID temperature control program supports workpiece heating up to several grams and hundreds of tons, and its fast characteristics can be used for fast temperature control in seconds;
2) In the process type PID closed-loop program, the inert link transfer function is added to solve the measurement delay problem of the temperature signal. The exponential/logarithmic reduction operation can quickly restore the actual temperature of the workpiece. Now, whether it is thermocouple temperature measurement or infrared temperature measurement, excellent fast and no overshoot PID temperature control can be realized;
3) Temperature change rate controllable: Automatically raises and lowers temperature according to a certain slope.
2, With energy control features: The integration of power versus time can be controlled, which is very effective for constant temperature control, quenching, relatively fixed workpieces and processes, and can meet high level and complex process control requirements.
3, Accurate and fast internal control : Comprehensively improve system accuracy and speed, current display and control resolution is extremely high, stable output does not fluctuate, control speed is not affected;
4. The fast automatic phase-frequency tracking technology based on the reactance analysis method solves the defects such as phase instability fluctuation of the 90° period latching method, sometimes entering the capacitive area switch, frequency shift causing phase shift, and small traceable range; Therefore, the IGBT switching loss is greatly reduced in the high frequency state.
Replacing the sensor or load change automatically and quickly tracks the resonant frequency and phase, ensuring that the power supply always operates at the optimum operating point. No adjustment parameters are required. The same model can guarantee an accurate IGBT zero-crossing switch in a frequency range as wide as 10 times.
5. Working mode: You can choose constant current or constant power output.
6. The system adopts the self-innovated fast IGBT drive circuit: Compared with the current drive circuit, it can significantly improve the resonance waveform, reduce the dead time, further reduce the switching loss, and increase the stability of the frequency tracking. At the same time, each IGBT drive is With short circuit protection and under voltage protection;
7. Uninterrupted operation design: In the case of rapid switching or flickering of the power supply circuit or accidental protection, the device can perform automatic diagnosis and automatically return to normal operation state (automatic restart), which can avoid production loss caused by shutdown. ;
8, The grid voltage adapts to a wide range: can adapt to -30% - +10% of the grid fluctuation range (three-phase 380VAC models). And under the control of the DSP, the output operating value is not affected by the grid voltage fluctuations;
9. The output of the device is not equipped with transformer type, with transformer type, with transformer cord and long portable type, which can be used by our company according to the diversity of customer heating process and the special nature of the working condition. ;
10, Local fixed output function: Can be fixed in the digital fixed amount, the potentiometer shift will not affect the output, this function can be combined with the timer and energy control function;
11. The device has power, resonant voltage, volts, temperature limit function, and has over-limit protection function;
12, Fault detection and protection functions complete: A complete fault detection and protection circuit, real-time monitoring of water shortage, overheating, over-voltage, over-current, lack of equal faults, rapid response, the cause of the fault is displayed on the display at the right time, and the synchronization indication Light indication; in addition, relay signals can be output from the output for external system coordination.
13, Friendly human-computer interaction: Human-computer interaction can choose a variety of ways, LED indicator or digital tube display, touch screen display and control, text screen display, customers can choose as needed; comprehensive coverage from function implementation and operation settings The traditional mechanical button panel makes operation and maintenance simpler, more intuitive and more convenient;
14. Hardware isolation interface: It can be compatible with the existing PLC on the market, which is beneficial to the customer to modify the existing PLC system and further expand the automation system.
15. Remote communication interface: Perfect communication control function, support RS-232C/RS-485/CAN interface, can realize multi-machine network monitoring and control, default RS485 adopts common MODBVS communication protocol; 4-20MA or 0-10V interface It can support closed-loop control with external systems, such as temperature closed-loop control systems.
16. Reasonable layout of internal components of the equipment: The main control circuit board is placed on the weak current side to avoid interference of the strong electricity to the control circuit and improve the control precision.
