Delta Electronics Electrical Maintenance Interview Questions and Answers

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more potential energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)

An insulator is a material that does not conduct electricity, heat, or sound.

• Insulators prevent the flow of electricity, heat, or sound.

• Common insulating materials include rubber, glass, plastic, and ceramic.

• Insulators are used to protect against electric shocks, prevent heat loss, and reduce noise transmission.

• Insulators have high resistance to the flow of electrons.

Servo drive installation involves setting parameters for optimal performance.

• Ensure proper power supply and grounding for the servo drive

• Set the motor and feedback device parameters correctly

• Adjust the velocity, acceleration, and deceleration parameters for smooth operation

• Calibrate the servo drive to match the mechanical system it is controlling

Mitsubishi AC drives parameters are settings that control the operation of the drive.

• Mitsubishi AC drives parameters include settings for speed control, acceleration, deceleration, and torque limits.

• Parameters can be adjusted using the drive's keypad or through software.

• Examples of parameters include frequency reference, motor overload protection, and fault diagnostics.

• Proper parameter settings are crucial for optimal
