Smooth start, Quick and quiet Moving
VVVF drive ensures Passenger Elevator operate more smoothly. Nice noise control brings passenger peaceful riding experience. The start, acceleration, brake curves are designed according to the ergonomic theory in order to get the finest coziness. It is a genuine current vector control variable frequency drive system. The permanent magnetic synchronous drive saves up to 48% in energy consumption.
High Precision Positioning Control System: Car displacement tracking technology ensures the leveling safety. Car-displacement-detection technology with high accuracy makes almost perfect leveling between the car and the landing level.
Applies advanced VVVF variable voltage and variable frequency control technology to the elevator door operator system so as to ensure the smooth elevator door and quiet switch. The self-learning door load detector increases the sensitivity of the elevator door switching on/off, monitoring variation on every floor to guarantee security and reliability.
