 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

 Preferably adjust only the parameters visible in the list User. Some of parameters mentioned are 
available only after contacted OMARLIFT Support. 
For departures "sweet" and without tearing it is necessary that the cabin moves slightly before acceleration 
begins. This is obtained with the parameters: 
THE  CABIN  AT  THE 
FIRST MOVE UP THEN 
DOWN 
SUDDEN 
ACCELERATION  AT 
START 
CABIN  ACCELERATION 
TOO FAST 
↑ increase the value of the parameter 
↓ decrease the value of the parameter 
= parameter has no effect 
•  Setting the STOP DOWNWARD 
 Preferably adjust only the parameters visible in the list User 
To get an accurate and "sweet" stop, with minor variations in load, it is necessary to adjust some parameters: 
ARRIVAL  TO 
FLOOR  STILL  IN 
DECELERATION 
(NOT AT CONSTANT 
SPEED) 
STOPPING 
BEFORE 
THE 
FLOOR
