Product advantages; powerful control platform; The ED3500 series inverter control core-based 32-bit RISC microcontroller, its speed of operation of 1.3DMIPS efficient completion of complex motor control algorithms to achieve true real-time control. Greatly improve the system's hardware peripherals integration and reliability. Leading the control algorithm in the the motor core control layer, ED3500 innovative vector control and VF control technology perfect combination of the introduction of the flux control thought, even in VF control mode can achieve good motor control, at the same time, the motor parameters insensitive to changes greatly improve the robustness of the system control. Open hardware architecture the ED3500 series of inverter provides powerful scalability SPI interface, open standard MODBUS protocol, on this basis, in the form of an expansion card to achieve any industry-specific functionality, without having to change the hardware of the host or software design, which greatly facilitate the secondary development of the client. 1, the standard V / F control, vector V / F control, separate type V / F control. 2, independent Waiyin the keyboard, native the keyboard and Waiyin keyboard dual control and inverter operation status monitoring. LED Waiyin keyboard, native keyboard features a simplified keyboard, can be achieved. 3, Serial communication: RS485 physical communication interface, embedded MODBUS protocol. 4, terminal control functions for the user to choose. The rich combination of frequency command, the maximum to meet the needs of all types of users. 6, the the intelligent motor speed tracking technology to deal with the power grid flashover. 7, intelligent power-saving features, customers can implement real-time monitoring of output power and accumulated electricity consumption query functions. Pull both current and sink current standard multifunction digital input and output terminals to switch signal compatible with any external devices on the market. High-speed pulse input output function, counter, wobble, the program is running, PID function as a standard feature design. 10, a comprehensive early warning, monitoring and protection functions. 11, the multi-carrier control method and the carrier automatically adjust the function of the good effect of the motor in the low frequency is the moment compensation. 12, superior overmodulation function can be improved voltage output capability, thereby increasing the output torque at high frequencies. 13, adopt the international standard MOUDBUS communication protocol, to facilitate the formation of a network control. Follow-up communications card launched to support a variety of bus protocol, to meet the needs of customers of all levels. The 14,4 line encoding LCD keyboard, keyboard operation is more direct, richer display. Users can from the manual operation. 15 high-power models can be equipped with a 5.7-inch touch-control screen function menu and the Help menu, innovative user interface, as operating their phones, so that the operator off now. 16, the full range of independent duct, which greatly improves the long-term reliability of the inverter in the textile, printing and dyeing, chemical fiber, paper, drawing, cement manufacturing and other industries for different applications environment. Product applications; the ED3500 series of products are widely used in paper, textile, CNC machine tools, petrochemicals, printing and dyeing, packaging, printing, ceramics, pharmaceuticals, and other fields, especially for the higher torque requirements of low-frequency equipment and supporting OEM customers. Can also be used in the field of variable frequency power supply, EPS. Note ED3500 series inverter, please note the following: 1, constant torque low speed inverter with ordinary motor long-term low-speed operation, due to the cooling effect of variation will affect the life of the motor. If you need long-term low-speed constant torque operation must use a dedicated inverter motor. , Confirmation of the motor insulation applications ED3500 series inverter with motor make sure the insulation of the motor to prevent damage to equipment. Also please regularly check the motor their environment is bad motor insulation, in order to ensure the security of the system. 3, negative torque load such as to enhance the load such occasions, there are often negative torque occurs, the inverter will produce an overcurrent or overvoltage fault trip, should be considered optional braking resistor. 4 the load device mechanical resonance points inverter output frequency range may be encountered mechanical resonance point of the load device, jump frequency must be set to avoid. 5, to improve the power factor capacitor or pressure-sensitive device due to the inverter output voltage pulse waveform, if the output side is installed to improve power factor capacitor or lightning varistors, cause damage to the inverter fault trip or device be sure to remove it, the other in the output side is not recommended to add air switch and contactor switching devices, as shown in Figure 1-3. (If you have to be connected on the output side of the switching device, the control must guarantee zero output current of the inverter switching action). 6, above 50Hz frequency run over 50Hz run, in addition to considering the motor vibration, noise increases, must also ensure the use of the speed range of the motor bearings and mechanical devices, be sure to confirm in advance. 7, elected with an adaptive motor motor electronic thermal protection value, the inverter can be implemented on the motor thermal protection. Motor with inverter rated capacity does not match, be sure to adjust the protection value or take other protective measures to ensure the safe operation of the motor. Altitude derating use at over 1000 meters altitude areas, causing deterioration of the cooling effect of the inverter due to the thin air, the use of necessary derating. Figure 1-4 shows the relationship between the rated current of the inverter and the altitude curve.
