11.4.1 Upwards
After the modify of the parameters of interest, it is always necessary to save the new values on
the hard memory of the Control Unit press the push button RAM to ROM, in order to prevent a loss of
data at the first shut down (voluntary or accidental) of the inverter. Using WEBSERVER software, you
have to switch ONLINE, then press the push button RAM to ROM. Alternatively, see the procedure
described to the chapter 10 for the setup by BOP.

Sequence controls Upward
1. Insertion of the UPWARD command then, when the contactors are closed, a signal has to arrive to
the ENABLE input: this will enable the starting of the motor.
If you enable the High speed or INSPECTION, the motor runs at a speed "high" or "inspection"
(P21507 (2.2.6) or P21514 (2.2.9)). If you do not enable any speed level (eg. During the re-leveling
at floor), the motor will run at the speed of re-leveling (P21515 (2.2.8)).
2. During normal running, when the elevator reach the command of slowdown, it should be taken off
the signal HIGH SPEED: in this way, the inverter automatically switches to "low" speed (P21512
(2.2.7))
3. Once on the floor, you have to open the UPWARD command, so the inverter reduce the speed of
the motor till to stop it, dropping the contactor command. As result of this operation, the command
ENABLE will be removed.
• Setting the START UPWARD
Preferably adjust only the parameters visible in the list User. Some of parameters mentioned
are available only after contacted OMARLIFT Support.
To have a good start, make sure that it is completely managed by the inverter. In this sense a
good way is to adjust the hydraulic valve to the maximum opening (it is the same operation
done, in installations without inverter, in order to have an instantaneous and rapid departure).
For "sweet" and without tearing departures it is necessary that the cabin moves slightly before the
acceleration begins. This could be done with the parameters P21502 (2.2.2), P21503 (2.2.3), by
tuning them properly. The subsequent acceleration phase is already set at the factory. If necessary,
you can make a different setting with parameters P21504 (2.2.4) and P21505 (2.2.10) visible in the
list User.
