
Setting the STOP UPWARD
Preferably adjust only the parameters visible in the list User S120_Low. Some of parameters
mentioned are available only in the list User S120_High.
The slowdown starts when you remove the command HIGH SPEED, and the UPWARDS command
remains activated; once the elevator get on the floor, you will take off the UP command and the engine
is automatically set to zero speed.
To achieve the desired accuracy of the stop, adjust the parameters P21512 (2.2.7) (Low Speed) and
P21513 (2.2.14) (Deceleration Final).

The stopping accuracy should not be affected too much by the load in the cabin or oil temperature, as
have been calculated with the appropriate automatic compensation.
If the situation on the arrival on the floor isn't satisfactory modifying the load or temperature, proceed as
follows:
-
Adjust the stop with cold oil and empty car, acting on the parameters P21512 (2.2.7) and P21513
(2.2.14).
- Repeat the test at the same temperature, but at full load and if necessary to adjust the accuracy of the
correct destination, this time to act on the parameter PX8 (DO NOT CHANGE the parameters P21512
(2.2.7) and P21513 (2.2.14)!)
-
Make several trips to heat the oil, oil heat control the stopping accuracy. If the car stops before the
floor, modify the parameter PX2 until you have the desired accuracy.
-
Finally, check with cold oil and empty car that stopping accuracy remained the one obtained with the
initial tests, otherwise repeat the procedure.
