4 - Check the slowing phase. The lift must reach the floor in a very small space (few centimetres) , at
constant speed without oscillations or vibrations, both for up and down directions. Adjust the space
travelled at low speed with parameter 2.2.4 (Deceleration ramp).
IMPORTANT: Considering the high precision of the inverter, it is important to set the
position of the slowing command with the best possible accuracy, to have the
same space travelled at low speed for any floor.
5 - If,
at floor arrival
, the car is not perfectly aligned with the floor, even if the stop switches are centred
to the floor, the parameters to be adjusted are:
If it stops BEFORE If it stops AFTER
2.2.5 Final deceleration ramp
2.2.8 Low speed level
A very good comfort can be obtained (for a 50 Hz rated frequency lift motor) with a 3Hz low speed and a
0,8 seconds final deceleration(P2.2.5).
9.1 – DIRECT ARRIVAL AT FLOOR FUNCTION
This function is available for all types of motor, for CLOSED LOOP configuration.
To enable it, parameter P.2.2.21.6 "stop distance" must be set at a value different from 0 and equal to the
stopping distance (distance
½ D - see figure below).
Recommended value ½
D is about 100 mm 100 - 150 mm (D = 200 - 300 mm.). Longer or shorter distances
are possible depending on the lift speed.
