Supplementary Explanation of Obstacle Detection Function of The Door
䃂 Carry out the obstacle detection of the door according to the following four
major reasons for detection.
Safety sensor must be input in the main controller of the elevator and in the
terminal of the main controller, operate the obstacle detection of the door.
Obstacle detection function of the inverter does not operate in CLOSE
arrival area.
Dual security measures must be taken.
Failure to do so could lead to injury.
Apply the obstacle detection function of the door after ensuring the security
and function operation of the elevator.
Failure to do so could lead to injury.

1. Start the fault ON operation according to obstacle detection.
2. Start the subtraction operation of OPEN arrival hold time (parameter P71) timer according
to OPEN arrival signal.
3. When the time of OPEN arrival hold time timer is up, fault ON operation produced by
sandwich is eliminated.
4. After eliminating the fault operation produced by sandwich, CLOSE operation is started.
(If the four major reasons for detection aren't eliminated completely, obstacle detection
signal will not be turned OFF.)

䋪Parameter P68 ( start confirmation time ) is the function to be used to prevent the
fault operation produced by obstacle detection.
