YASKAWA Europe TOEP C710616 92D AC Drive L1000H Quick Start Guide EN 25
Speeds must be set so that Nominal Speed > Intermediate Speed > Inspection Speed > Leveling Speed. The speeds are
set as m/s values in parameters P1-16 to P1-19. These values are calculated for P3-01 to P3-04 as frequency references
and must keep the rule P3-01 > P3-02 > P3-03 > P3-04. Not keeping this rule will cause oPE12 alarm. Correct settings
and repeat teaching function.
In case that more than one speed selection input is closed, always the lowest speed will be active.
In case that the drive is running with a speed which is slower than nominal speed, the sequence is slightly adapted, to
ensure shortest possible run time with maximum comfort.
In case of Nominal Speed (no overload case), the drive starts deceleration to Leveling Speed immediately when opening
the speed selection input. In case that the drive runs with a slower speed, the deceleration to Leveling Speed is delayed by
a time, calculated automatically by the drive. Refer to the figure below.
Re-leveling RUN
Travel Stop
The drive will cancel normal procedure in the following cases:
• The Run command is removed while the Speed Selecting input is still closed or the drive is decelerating to Leveling
Speed
> SEQF fault shown and coast to stop (immediate power off).
• A digital input, set to “External Fault” (refer to parameter in section 6), is activated
> stop as defined by the input.
• Removing the wire link from the safety inputs (H1, H2, HC) or activating a digital input, set to “Base Block”
> coast to stop.
