MCDKT3520CA1 Panasonic three phase 750w power output servo driver

 

Due to the fact that PLC only depends on the state of the input relay coil in its memory when running a program to determine the on/off status of contacts, and does not directly identify external devices, the selection of external devices during programming is closely related to the type of contacts in the program. This is a problem that is prone to occur when comparing PLC programming with electrical control schematic diagrams. The most typical example is the parking control in the basic control - "start stop control". Figure 2 shows the electrical schematic diagram of "start stop control". In this system, button SB0 is used for parking control, so its normally closed contacts are connected in series to the control circuit. SBl is a start button that uses its normally open contact. If the same equipment is used (i.e. normally closed contact for stopping SB0 and normally open contact for starting SBl), PLC is used for this control,
 
The parking signal X0 in this ladder diagram uses normally open contacts connected in series in the control circuit, which is caused by the external parking equipment selecting the normally closed contact of the button. If the button is not operated, the output Y0 is normally connected. If the button is pressed, the output Y0 is powered off.
 
The function of a servo amplifier is to compare, amplify, and calculate the input command signal (voltage) with the system feedback signal (voltage), and output a deviation voltage signal
 
Proportional control current is applied to the torque motor control coil of the servo valve, controlling the opening of the servo valve core and providing amplitude limiting protection.
 
Parameter requirements for servo amplifiers
 
As an electronic device for driving electro-hydraulic servo valves, servo amplifiers have certain requirements for their corresponding parameters:
 
(1) The input voltage is within ± 10 V, which facilitates the control of command components such as computers and programmable controllers:
 
(2) Output current ± 10-+100n approved adjustment to adapt to various models of torque motor servo valves;
 
(3) The linearity error of the servo amplifier is less than 3% Fs;
 
(4) Having a feedback access terminal to form a closed-loop control system;
 
(5) To adapt to the high-frequency response characteristics of the servo system, the servo amplifier has a bandwidth greater than 1200 Hz;
 
(6) It has the function of limiting large output current and protecting against output short circuits, which can limit the large flow rate of servo valves and prevent faults caused by output line short circuits.
 
The principle of servo amplifier
 
The servo amplifier is composed of modules such as command and feedback comparison processing, zero adjustment circuit, current limiting circuit, preamplifier, power amplifier, etc. Its structural diagram is shown in Figure 2
 
As shown in.
 
The function of the preamplifier circuit is to compare and amplify instructions and feedback input signals. The circuit K Fbk represents the input signal and feedback signal, respectively
 
Adjust the circuit gain through the potentiometer to meet the requirements of the power amplifier circuit, so that the circuit voltage can match the front and rear stages.
 
The function of the zero adjustment circuit is to adjust the circuit reference voltage by adding an adjustable voltage to the preamplifier circuit. By adjusting the potentiometer to compensate for zero bias
 
Server amplifier system bias.
 
The function of the current limiting circuit is to limit the large current flowing through the servo valve coil, avoid coil overload, protect the servo valve, and limit the large flow rate of the hydraulic system. This circuit is composed of an operational amplifier
 
ULD, U2A, diode D D: And adjustable voltage source through potentiometer R., Adjust the amplitude of the input voltage of the power amplifier stage to reach the limit output
 
Current output purpose. The function of a power amplifier circuit is to convert and amplify a low-power voltage signal into a high-power current signal, in order to provide sufficient servo valve rating
 
The current is used to drive the load, and it requires good anti-interference ability and static and dynamic performance. This circuit utilizes the poles of NPN and PNP type transistors to generate
 
The stages are interconnected, with signals input from the base and output from the emitter. The circuit can be seen as a combination of two emitter outputs, forming a push pull power amplifier
 
The circuit operates within the positive and negative half cycle of the input signal. In addition, a high-frequency rated vibration signal generated by the 8038 chip can also be added to the output current to improve
 
High servo valve resolution and prevention of valve core sticking due to Coulomb friction.
 
Calculation of output current of servo amplifier
 
The servo valve coil is the load of the servo amplifier, which is equivalent to the inductive impedance composed of 0.3H inductance and 800 resistance. In order to make the output control current of the power stage proportional
 
Dry input voltage signal, using an electric cathode. Connect with the load coil and feedback the voltage on it to the inverter input of the amplifier through the cathode, achieving closed-loop control
 
Control and adjust the output current of the power stage, because the feedback voltage of the power stage is generated by the current, it is called current negative feedback. After introducing current negative feedback, the rated voltage
 
Within the load range, the change in load impedance does not affect the change in output current of the power stage, and the servo amplifier acts as a constant current source.
 
The function of the preamplifier circuit is to compare and amplify instructions and feedback input signals. The circuit K Fbk represents the input signal and feedback signal, respectively
 
The gain of the circuit is adjusted through the potentiometer to meet the requirements of the power amplifier circuit and make the circuit voltage match the front and rear stages.
 
The function of the zero adjustment circuit is to adjust the circuit reference voltage by adding an adjustable voltage to the preamplifier circuit. By adjusting the potentiometer for zero offset compensation, the signal

High servo valve resolution and prevention of valve core sticking due to Coulomb friction,
 
The output current of the servo amplifier is calculated as the load of the servo valve coil, which is equivalent to the inductive impedance composed of a 0.3 H inductance and an 80 Q resistance
 
The output control current of the power stage is proportional to the input voltage signal, and a resistor is used. Connect in series with the load coil and feedback the voltage on it to the amplifier through a resistor
 
The reverse input terminal of the power cooling stage achieves closed-loop control and adjusts the output current of the power stage, because the reverse voltage of the power cooling stage is generated by the current, it is called current negative feedback. already
 
After the negative feedback of the input current, within the rated load range, the change in load reactance basically does not affect the change in output current of the power stage, and the servo amplifier is equivalent to a constant current source.
