■ Short Floor Function
Short Floor automatically adjusts the speed in order to reduce the leveling time if leveling speed was activated before the
selected speed was reached. Short Floor is enabled setting S5-01 = 1. The drive calculates the distance to decelerate from
rated speed to the leveling speed, then controls the stop so that the stopping time is shortened. In
Figure 55 below, area S
indicates the distance for a stop from nominal speed.

Figure 55 Speed During Normal Operation
<1> The drive will recognize the speed reference that is lower than the Leveling Speed Detection Level (d1-28) as
the leveling speed if the speed priority is set for multi-step speed reference (d1-18 = 0 or 3).
Advance Short Floor
Advanced Short Floor minimizes the operation time to arrive at a designated floor. It uses the leveling speed once the
leveling speed command is entered via one of the multi-function inputs (H1-
= 53). Advance Short Floor calculates
optimal speed based on the Short Floor Minimum Constant Speed Time (S5-03) and the currently selected deceleration
rate.
