How does it work?
The Quick Stop function is configured using BICO parameters and they are explained in the table
below.
Table 8-39 Quick Stop parameters
Parameter Description Remarks
P0881 Quick Stop function Input 1 is ON Allows Quick Stop source 1 command to be selected using BICO.
The signal is expected to be active low (default setting P0886 =
2).
P0882 Quick Stop function Input 2 is ON Allows Quick Stop source 2 command to be selected using BICO.
The signal is expected to be active low (default setting (P0886 =
2).
P0883 Quick Stop override Allows Quick Stop override command source to be selected us‐
ing BICO. The signal is expected to be active high.

When the Quick Stop function is activated, an OFF1 command is initiated. The motor will be
slowed and brought to a standstill using the ramp-down times set in parameter P1121. The
default setting for P1121 is 10 seconds and this value may need adjusted to ensure that the 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 converter 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:
