6.5.8 Setting parameters for short floor operations
(FUN_56, FUN_57)
When the multistep speed operation is used to control elevator speed, repeated
short trip patterns can reduce the overall riding quality of the elevator. Use the
inverter’s ‘Short Floor’ function to improve elevator speed control FUN_56
(ShortFlr speed) and FUN_57 (ShortFlr time).
The inverter’s short floor control is for acceleration speed only and is not
available in the features dedicated for elevators that use ELIO.

For example, when multifunction input terminals P1 and P2 are set to “Speed-L”
and “Speed-M,” and if FUN_12 and FUN_13 are set with smaller values the
setting at FUN_56, and the setting at FUN_14 is greater than the settings at
FUN_56, the following operation becomes available. (Set FUN_57 to “0” or other
fixed value).
Example 1: Elevator running speed is less than the short floor speed and the
short floor speed is not set at “0”.
When the motor starts and accelerates in the forward direction and multifunction
input P2 is ON, a new speed reference is calculated if the signal at P2 is OFF. If
the new speed reference is less than the speed set at FUN_56 (ShortFlr Spd),
the motor accelerates to the new speed reference and maintains the speed for
the time set at FUN_57.
After the operation time has elapsed, the motor runs at the speed set at
FUN_12.
Use the following formula to calculate the new speed reference.
•
New speed reference = Current speed + ([FUN_04]
ⅹ
[FUN_37])
If FUN_37 is set to “0”, the current speed becomes the new speed reference.
