Servoamplifiers and inverters

The servo mechanism processes input signals into output signals. Usually the input signal is different from the input signal, e.g. the input signal can be the pulse duration and the output signal the axis rotation angle. Servomechanisms allow you to control the position, speed and torque. The electric motor in cooperation with the inverter (frequency converter) allows for smooth speed regulation. Servo components are: - input signal stage, responsive to the transmission of control signals; e.g. PLC controllers with positioning modules; - part of the controllers is a section of signal processing, receiving feedback signals of the motor position from the encoder and issuing them to the motor. Servo amplifiers are this part; - the part related to the drive, which are servomotors (servo motors). Servo drives usually have a built-in encoder with connector, servo motor shaft and power connector connecting with power supplies. The function of servo amplifiers and frequency converters is similar. The main difference, however, is that the servo amplifier uses a dynamic brake, absorbing the inertia energy of the servomotor.
