load on the conveyor section is brought to a halt at the correct position on the conveyor
section
Setting the ramp-down time too short can cause the Inverter to trip with either and
overcurrent or overvoltage fault.
The controlling system detects that the Quick Stop function has been activated and can, by
use of the appropriate ON command or the 'Quick Stop override" signal restart the motor as
required.
Using parameter P0886, it is possible to set the type of reaction required to stop the
conveyor section. There are basically two trigger methods, edge triggered signals or level
triggered signals. Each type of triggering method produces a different reaction to the OFF1
command and the restarting of the motor. These reactions are shown in the figures below:
Figure 8-35 Positive edge triggered signals reactions
Figure 8-36 High level triggered signals reactions

Limit position and limit switch
A limit position is a position in the direction of m
o-
tion o
f a machine component at which the motion
stops due to the construction. A limit switch is a
sensor that signals that the limit position has been
reached.
