ElevatorPG card MCTC-PG-E synchronous inverter frequency division card

The elevator PG card, or position detection card, is an important component of the elevator control system. ‌Its main function is to detect the operating position of the elevator and feed this information back to the control system for precise position control and scheduling. The PG card is connected to the encoder of the elevator traction machine to achieve closed-loop vector control, ensuring the smooth operation and accurate parking of the elevator.
