MDMA102P1G picture MDMA102P1G model MDMA102P1G Guangzhou Matsushita servo motor agent Zhang Gong 182-019-88-309 QQ 8788-56087 following areas: performance and advantages of Panasonic servo motor products, use, service, packaging and other goods of price; servo amplifier The principle of the servo amplifier comparison processing by the instruction and feedback, nulling circuit, current limit circuit, preamplifier, power amplifier modules and other effects, and its block diagram shown in Figure 2. , Preamplifier role is to command and feedback input signals are compared and amplified. The circuit K. , Fbk are the input signal and the feedback signal, through a potentiometer j dagger gain adjustment circuit, to adapt them to the requirements of the power amplifier circuit, so that before and after the circuit reaches a voltage level matching. Zeroing circuit is effected by the superposition of an adjustable preamplifier circuit voltage, the reference voltage adjustment circuit. By adjusting potentiometer as zero bias compensation to overcome the bias servo amplifier system. Limiting circuit's role is limited to the maximum current flowing through the coil servo valve to avoid coil overload protection servo valves, hydraulic systems to limit the maximum flow. The circuit consists of op amp ulD, U2A, a diode D. , D: and adjustable voltage source constituted by the potentiometer R. , Adjust the power amplifier stage of the amplitude of the input voltage, the output current limit is reached purpose. Power amplifier circuit is the role of low-power voltage signal into a power amplified for large current signals to the servo valve to provide sufficient current rating, to drive a load. And requires a good anti-jamming capability and static and dynamic performance, the circuit uses NPN and PNP transistor base and emitter connected together, the signal input from the very base, emitter outputs. Circuit can be seen as a combination of two emitter follower formed, constituting the push-pull power amplifier circuit, respectively, within the input signal positive and negative half-cycle work. In addition, also superimposed on the output current signal of the high frequency chatter generated by a 8038 chip, in order to improve the resolution of the servo valve and prevent Coulomb friction caused by catching the spool.
