Upwards - Siemens S120 Instructions Manual

10.4.1 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 (Copy from RAM to ROM), in order to prevent a loss of data at the
first shut down (voluntary or accidental). Using STARTER software, you have to switch ONLINE, then
press the push button Copy from RAM to ROM

1. Insertion of the UPWARD command then, when the contactors are closed, a signal has to arrive
to the
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 S120_Low. Some of parameters
mentioned are available only in the list User S120_High
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 S120 High.
