APPENDIX 1. POSITIONING
Positioning of the elevator implies to following the car position in the elevator shaft. In order to know the right
position magnetic sensors (monostabil and bistabil) and inductive switch are used.
Acording to the configuration, type of elevator (electric, hydraulic) and speed of the elevator there are 5 types of
posittioning sistem which is set through parameter E-01.
With any type of posittioning elevator always goes to first drive after switching the power on, switching from
inspection drive to normal drive, or switching from recall to normal drive. When using possitioning type 1-3 first drive is
only in one direction (adjustable through parameter E-02) while when using positioning type 4 or 5 first drive direction
is to down floor and then up to the last floor.
In the first drive elevator slows down when reaching the referent switch (up or down), same is in the normal drive,
while slowing down for other floors is counting sensor switch or the impulse from the inductive switch depending on
the positioning type.
Positioning type 1:
It is used for one speed elevators. Two bistabiles are used for final floors, and monostabile switch for stopping in
the floor level.
Positioning type 2:
It is used for two speed elevators (regulated or not regulated). It is usually used when the deceleration distance is
higher than ½ of the floor to floor distance.
Two bistabiles are used for final floors, one monostabile switch for stopping in the floor, and two monostabiles for
counting the floors and slowing down. Slowing down for first and the last floor is referent switch and for other floors
slowing down is counting switch up or down according to direction of travel.
Positioning type 3:
It is used for two speed elevators (regulated or not regulated). It is usually used when the deceleration distance is
lower than ½ of the floor to floor distance.
Two bistabiles are used for final floors, one monostabile switch for stopping in the floor and one bistabile switch
for counting the floors and slowing down. Slowing down for first and the last floor is referent switch and for other floors
slowing down is counting switch.
Positioning type 4:
It is used for two speed elevators (regulated or not regulated). It is used when having annular gear on the
overspeed guvernor or frequency inverter with close loop connected to CAN.
Two bistabiles are used for final floors, one monostabile switch for stopping in the floor or optical sensor, and
inductive switch on the overspeed guvernor. Slowing down for first and the last floor is referent switch and for other
floors slowing down is impulse information from the inductive switch.
Positioning type 5:
It is used with frequency regulated elevators with two high speeds when the speed is so high that when driving
froom floor to floor there is not enough space to accelerate to nominal speed before slowing down. In that case
possitioning 5 is used and the speed between two floors is lower than nominal speed of the elevator.
Two bistabiles are used for final floors for high speed, and two bistabiles for lower speed, one monostabile switch
for stopping in the floor and inductive switch on the overspeed guvernor.
Slowing down for first and the last floor is referent switch and for other floors slowing down is impulse information
from the inductive switch.
First drive is done with lower speed in down direction and up direction. In normal drive speed from floor to floor is
lower while when driveing two or more floors speed is nominal.
