A. Product overview

Electronic technology's rapid development, new electronic and power components continue to produce, so that control system functions and performance produce a great leap, traditional analog circuit electric actuator has not yet met the requirements of control system, new intelligent digital electric actuator, with its rich functions, excellent performance, excellent human-machine interface, has been widely used. Intelligent digital electric actuator's mechanical design and traditional analog electric actuator is essentially the same, forming an intelligent digital electric actuator, combining servo amplifier, position transmitter together, forming a new electronic circuit, completing input and interface technology, adding unique CPU troubleshooting, recognition and logical judgment, in the performance aspect, using software technology, completing adaptive positioning calculation, making positioning errors smaller, control accuracy improved, compensating the mechanical design deficiencies, servo motor control adopts over zero trigger controllable silicon power device, control method simple, field debugging is very convenient, improving the whole machine operation reliability, its electrical control features are as follows:

1.Electrical control circuit adopts microprocessor (CPU) hardware, software technology makes the field debugging very simple, through the on-site operation button (manually open)

Go to the debugging menu, run the valve position to open limit position, confirm, and then close to limit position (mechanical positioning upper and lower limit), confirm that the internal microprocessor will automatically recognize these two limit locations, and store their numerical values. Go to the debugging menu, run the valve position to open limit position, confirm, and then close to limit position (mechanical positioning upper and lower limit), confirm that the internal microprocessor will automatically recognize these two limit positions, and store their numerical values. Valve bit signal output (4-20mA), software calculated, automatically corresponds to the actuator start point to end point range, field debugging work can be completed.
