Which parameter does the elevator controller monitor to adjust the car's movement?

• A. Load
• B. Temperature
• C. Humidity
• D. Voltage

Answer: (A)

The movement of an elevator car is governed by the load inside it. The controller uses sensors to estimate how heavy the car is (passengers and cargo) and then adjusts motor torque and acceleration so the car moves smoothly and safely between floors. If the load is too high, the system will limit speed or stop to protect the wrecking of components and ensure passenger safety. Temperature and humidity are monitored mainly for equipment protection and environmental reasons, not to drive the car’s motion. Voltage relates to the electrical supply, which must be adequate, but it isn’t the parameter the controller uses to directly determine how the car moves.
