The SFC−LACI cannot function autonomously, i.e.it does not
have its own user program. However, record switching can be
used to define a sequence of records.
There are also 3 records with special functions (which cannot
be executed in Record selection mode):
 Record 32 contains the parameters for the Jog mode.
 Record 33 contains the
parameters for Direct mode.
 Record 34 is the direct set for the FCT software.
Direct mode
In direct mode (also called direct order) positioning tasks are
formulated directly in the output data of the master.
Positioning mode The typical application dynamically calculates the target
setpoint values for each job or just for some jobs. Adaptation
to different workpiece sizes is therefore possible. It is not
sensible here to parameterise the
record list again each time.
The positioning data are managed completely in the PLC and
sent to the SFC−LACI.
Operating modes of the SFC−LACI: Profile Position Mode"
Force mode Alternatively, setpoint values relative to the rated motor
current can be specified in direct mode. With linear motors,
this results in a force (force control).
Operating modes of the SFC−LACI: Profile Torque Mode"
FHPP Continuous Mode Continuous setpoint specification: Specification of
changeable position values at millisecond frequency
(typically 4 ... 10 ms).
