L34 Elevator Parameter (Moving distance in creepless operation)
L34 specifies the moving distance of an elevator car in a creepless operation from its start to end.
- Data setting range: 0.0 to 6553.5 (mm)
Creepless operation
If creepless operation is set with the function codes listed below, the inverter receives the landing
reference position of the elevator car by an external command, and generates a speed command
profile so that the car travels the distance specified by L34 from the reference position to land the car
in the correct position.
Accordingly, the creepless operation eliminates the creep required for general elevator control,
reducing the landing time duration.

L31 Elevator speed 1 to 4000 mm/s
This code specifies the
elevator speed relative to the
inverter's maximum speed.
L34
Moving distance in
creepless operation
0.0 to 6553.5 mm
This code specifies the
moving distance of an elevator
cage in a creepless operation
from its start to end.
Requirements for creepless operation
(1) The elevator system should be equipped with a device that accurately detects the position of an
elevator cage, or its equivalent device.
(2) The elevator system should be capable of applying signals issued from the detector (stated in (1)
above) to the inverter as a "Start creepless operation" command
CRPLS
or be capable of
modifying speed commands (except zero speed) to zero speed command.
(3) During deceleration, that is, after the start of deceleration, the signal stated in (2) above can be
applied to the inverter.
(4) The moving distance from the start of a creepless operation should be 6553.5 mm or less.
(5) The elevator speed calculated for L31 should be 4000 mm/s or below.
(6) A multistep speed command with S-curve operation should apply for speed control.
