1.6 Landing System

Once the car is running smoothly, install the landing system (see the CEDES/ELGO Installation Manual).

After the landing system has been installed, run the car, and observe the actual vs. demanded speed of

the elevator. The CEDES landing system is very accurate, and the elevator speed can be observed on the

main display screen under "FPM: __". However, a tachometer can also be used to verify the speed

displayed. If the car is running faster or slower than demanded, change the following:

Induction motor:

Magnetek:

Adjust (A0) -> Drive (A1) -> Contract Motor Speed -> reduce the RPM if the car is running

faster than the demanded speed / increase the RPM if the car is running slower than

demanded speed. (Good values to start with are +/- 10RPM).

KEB:

Machine Data -> LN01 -> change the sheave diameter until the speeds match (good

values to start with are +/-1 RPM).

Permanent Magnet motor:

It is rare for a gearless machine to run at a different speed than the one demanded, but if

adjustments are needed, the same method stated above applies. Note that if the rope ratio is 1:1,

the RPMs will only need to be adjusted by a very small amount. (Good values to start with are +/-

1 RPM).
