1. System overview
The SFC−LACI has three types of memory:
FLASHThe FLASH memory stores the default settings and the firm
ware. The data from the FLASH memory are loaded when the
device is switched on the first time or when the EEPROM has
been deleted.
RAMThe volatile RAM memory stores the parameters that are
currently being
used and which can be modified using the
control panel or FCT. When the modifications have been
saved, they are transferred to the EEPROM.
EEPROMThe non−volatile EEPROM stores the parameters that are
loaded when the device is switched on.The parameters in
the EEPROM are retained even after the power supply has
been switched
off.
To restore the default settings, the EEPROM can be deleted
via the CI object 20F1h (see section B.1). User−specific set
tings will then be lost.

Check within the framework of your EMERGENCY STOP
procedures to ascertain the measures that are necessary
for switching your machine/system into a safe state in the
event of an EMERGENCY STOP.
· If an EMERGENCY STOP circuit is necessary for your ap
plication, use additional, separate safety limit switches
(e.g. as normally closed limit switches wired in series).
· Use hardware limit switches or, if required, mechanical
safety limit switches and fixed stops or shock absorbers
as appropriate in order to make sure that the axis always
lies within the permitted positioning range.

· When doing this, pay attention to the FCT diagram

Project zero point PZis a point to which the actual position and

1.6.1Homing methods to switch with index search
The following can be used for homing to a proximity sensor:

mended). It is located on the retracted (negative) end
position and must not be moved (exception: minimum
offset with an Index pulse warning", see section 6.4.1).
2. A proximity sensor to be externally attached by
The proximity sensors can be configured as reference
switches or as limit switches. This means homing either runs
to the reference switch or to the limit switch.
If a proximity switch is configured both as a reference switch
and as a limit switch, then its signal during homing is inter

in the opposite direction. If a reference signal is found there,
the drive runs through the
switch. The homing point is subsequently the following index
pulse at the end of the switching range.

extends over the nearest fixed stop (or end position).
There must no range between the limit switch and fixed

Warning
· Use only PELV circuits as per IEC/DIN EN 60204−1 for
the electric power supply (protective extra−low voltage,
PELV).
Take into account also the general requirements for
PELV circuits as per IEC/DIN EN60204−1.
· Use only power supply units that guarantee reliable
electrical isolation of the operating voltage as per
IEC/DIN EN 60204−1.
Protection against electric shock (protection against direct
and indirect contact) is guaranteed in accordance with
IEC/DIN EN 60204−1 by using PELV circuits (electrical equip
ment of machines, general requirements).
Note
Note that the tolerances of the voltage supply must also be
observed directly at the voltage supply connection of the
SFC−LACI.
· For the power supply, use only the cables specified in
Tab.3/2.
· Use closed−loop regulated power supply units that
comply with the requirements described in Tab.3/4.

Load voltage supply: The use of power supply units with
lower output levels is possible with restricted motion dy

3.2.1Function of the hardware enable
Application of 24 VDC to pin 3 (relative to pin 5) of the power
supply connection is essential for operation of the SFC−LACI.
In a similar fashion to the relay, Hardware Enable" switches
the load voltage on and off, whereby the voltage of the
hardware enable represents the control voltage:
Hardware enable applied:
the load voltage is switched
through.
Hardware enable missing: the load voltage is blocked.
Switching the voltage on or off of the Hardware Enable" is
thus equivalent to switching the load voltage on or off.
The Hardware Enable is electrically isolated.
Use of the Hardware enable is described in section 5.5.4.

3.3Earthing
Note
· Connect one of the earth terminals of the SFC−LACI at
low impedance (short cable with large cross−section)
to the earth potential.
You can thereby avoid interference from electromagnetic
sources and ensure electromagnetic compatibility in
accordance with EMC directives.
To earth the SFC−LACI, use one of the following terminals
(see Tab.3/3):
Earth terminal on
the housing of the SFC−LACI, or
Earthing strip with cable lug on the plug housing.
Note
Note that only one of the three earth terminals may be
used (to avoid earth loops).
When using the earth terminal on the housing of the
SFC−LACI:
· Use a suitable earthing cable with an M4 cable lug to
gether with the accompanying nut and toothed washer.
· Tighten the nut with max. 1.7 Nm.

Displacement encoder for BiSS interface
The BiSS interface is a 2−wire interface for interference−im
mune sensor connection. In contrast to the SSI interface, the
data transmission is bi−directional, which means, for example,
that data can also be written into the sensor for parametrisa
tion.
Data is transmitted via a pulse cable controlled by the master
and a data cable
mission. Data is written to the slave via the cycle’s pulse
width modulation in accordance with the "BiSS B mode" pro
tocol specification http://www.biss−ic.de/files/
BiSS_b3ds.pdf; the direc¬tion of the data cable is not
switched. Pulse and data are transmitted using RS485 tech
nology, which means a
inverted and issued at the receiver as differential input. This
suppresses common−mode interference. The data are also
secured by a CRC code.
The BiSS interface supports 2 read−out modes:
controlled by the sensor as serial trans
signal is sent not−inverted as well as
3−12
The sensor data channel for fast pulse out (pulse up to 10
MHz) of the sensor information
The
parameter channel for reading and writing sensor
parameters as well as for depositing user−specific data
protected against zero voltage in the sensor’s EEPROM
The distinction is made on the basis of the start bit, details
can be referred to in the specifications given.

5.2.1Setting the reference run parameters
Switch the SFC−LACI on. When the logic voltage is switched
on, the SFC−LACI carries out an internal check. The display
briefly shows the Festo logo then changes to the status dis
play.
The reference point is determined as follows, depending on
the homing method:
by means of the drive’s integrated reference switch with
subsequent index search (recommended) or
a
by means of a fixed stop (to be fitted externally by the
customer).
For homing to the switch, only the drive’s integrated refer
ence switch can be selected on the control panel. Use the FCT
for parametrising if you require further options.
5−8
The homing run process is described
in section 1.6.
You can set two different speeds for searching for the
reference point and for the subsequent run to the axis
zero point. The maximum speed is subject to built−in limits.

Note
Controller inaccuracies
If you do not enter the offset of the reference point,
control inaccuracies (e.g. overshooting) can occur with
small (100 mm) and large nominal strokes (400mm).
When homing to the drive’s integrated reference switch,
the reference point position is known (6 mm) and must not
be entered. This reference switch must
not be moved.
Caution
Damage to components when the permissible impact
pulse is exceeded.

Danger of injury!
Electric axes move with high force and at high speed. Colli
sions can lead to serious injury to human beings and dam
age to components.
· Make sure that nobody can reach into the sphere of in
fluence of the axes or other connected actuators and
that no items are within the positioning range while the

Caution
When the homing method is changed, the axis zero point
offset is reset to the factory settings (see section 5.2.4).
Existing parametrised software end positions and target
positions already set in the position set table are shifted
together with the axis zero point.

If the axis zero point is modified:
