Siemens SINAMICS G110D Operating Instructions Manual page 155

There are two sensors on the conveyor section, so that the Quick Stop function can stop the
conveyor section in either direction when a load is detected.
How does it work?
The Quick Stop function is configured using BICO parameters and they are explained in the
table below.
Table 6- 51 Quick Stop parameters
Parameter Description
P0881 Quick Stop function Input 1 is ON
P0882 Quick Stop function Input 2 is ON
P0883 Quick Stop override
r0885 Quick Stop status
P0886 Quick Stop input type
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 Inverter to trip with either and
overcurrent or overvoltage fault.
The controlling system, for example, the AS-i controller 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:

Remarks
Allows Quick Stop source 1 command to be selected using BICO. The
signal is expected to be active low (default setting P0886 = 2).
Allows Quick Stop source 2 command to be selected using BICO. The
signal is expected to be active low (default setting (P0886 = 2).
Allows Quick Stop override command source to be selected using
BICO. The signal is expected to be active high.
