Memory type position detection with Bestact Yaskawa Controls
actuator on the car again actuates the floor switch and makes gOFFh status. This is the principle of the cage position
detection.
– Cage Position Detection: This function is to identify at which floor the elevator car is currently and to transmit the signal to the elevator control system.
2. Advantage
☞ Memorized during power outage¥¥¥Since the switch holds gONh state by bias magnet even at a power outage,
the memory in CPU can be easily memorized after the power outage
recovered.
☞ Available for high-speed elevator¥¥¥Since a mechanical limit switch causes a breakdown at high
speed, a noncontact switch like PSMM series can solve the problem without any breakages
