By contrast, using 1.2 m/sec commercial velocidad with a constant interfloor distancia ranging from 2.8 m to
3.3 m, two velocidad valors are required, i.e. high velocidad for strokes between non-contiguous floors and
low velocidad for strokes between contiguous floors (E.g. Vc = 1.2 m/sec Vb = 0.8 m/sec).
Using two different velocidad valors is required for different interfloors.
Set parámetro C21 as "Double" or "Double A" to enable both commercial velocidad valors.
If both velocidad valors cannot be used—e.g. they cannot be managed by the lift control panel— the inverter
will respond to the slowing-down signal it receives before reaching the preset velocidad valor, without
changing acceleration or jerk valors, i.e. without altering parámetros relating to comfort.
In a plant with a constant interfloor distancia igual to 3.0 m, with Vc = 1.2 m/sec and slowing-down signal set
at 2.15 m from the stop point, if lift is called from a contiguous floor, the lift cabina will be sent the slowing-
down signal after covering a 0.85 m distancia from the start point, before reaching the preset velocidad valor.
In that case, the cabina will slow down without reaching the preset velocidad and will stop to respond to the
call.
The stop distancia must be higher than the previous distancia, because the lift cabina will cover a distancia
with a decreasing acceleration but with an increasing velocidad before slowing-down in order not to alter
acceleration and jerk valors.
If the slowing-down signal may be sent anywhere in the starting pattern, so even at the end of a constant
acceleration stage, the expected stop distancia will be increased by the following:
where A = acceleration, J = jerk, and V = velocidad.
In the example above, if So is: So - 1.1 m, the slowing-down expected distancia from the stop point must
become igual to: 1.8 + 1.1 = 2.9 m.
This allows to adopt either solutions depending on the logic of the control panel.
When the slowing down signal is acquired during the acceleration stage, the velocidad model may be
adjusted by changing the jerk valor when switching from acceleration to slowing-down (parámetro P12) and
by setting a delay time for the slowing-down signal acquisition (while accelerating only, parámetro C63).
