Atul Auto Interview Questions and Answers

Parameters for setting a Variable Frequency Drive (VFD) include frequency, voltage, acceleration/deceleration time, and motor overload protection.

• Frequency setting determines the speed of the motor.

• Voltage setting controls the voltage supplied to the motor.

• Acceleration/deceleration time setting determines how quickly the motor ramps up or down in speed.

• Motor overload protection setting helps prevent damage to the motor in case of excessive load.

Robots work based on a set of programmed instructions and use sensors and actuators to interact with their environment.

• Robots follow a set of instructions called a program.

• They use sensors to gather information about their surroundings.

• Actuators allow robots to physically interact with their environment.

• Robots can be programmed to perform various tasks, such as assembly, welding, or inspection.

• Examples of robots include industrial robots, autonomous vehicles, and robotic arms...read more

VFD stands for Variable Frequency Drive. It is an electronic device that controls the speed of an AC motor by varying the frequency of the electrical supply to the motor.
