How ac servo work with variable frequency inverter?
AC servo systems can use inverters, also known as variable frequency drives (VFDs), as the drive component. An inverter is an electronic device that converts a fixed frequency AC voltage to a variable frequency AC voltage. In an AC servo system, the inverter is used to control the frequency and voltage of the AC power supplied to the servo motor, allowing for precise control over the motor's speed and torque.
The inverter receives commands from the servo controller, which tells it how much power to supply to the motor, as well as the desired frequency and voltage. The inverter then adjusts the frequency and voltage of the AC power supplied to the motor, based on these commands. This allows the motor to operate at the desired speed and torque, and to accurately follow the controller's commands for position and velocity.
The inverter also provides some additional functions that are useful for AC servo systems. For example, many inverters have built-in protection features, such as overcurrent and overvoltage protection, which help to prevent damage to the motor or the inverter itself. Additionally, some inverters can provide feedback to the controller, such as motor current and voltage measurements, which can be used to further improve the control of the servo system.
