The SFC−LACI cannot function autonomously, i.e.Ăit 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):
ć Record 32 contains the parameters for the Jog mode.
ć Record 33 contains the parameters for Direct mode.
ć Record 34 is the 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 nominal
target values for each job or just for some jobs. Adaptation to
different workpiece sizes is therefore possible. It is not senĆ
sible 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 mode of the SFC−LACI: Profile position mode"
Force mode Alternatively, setpoint values relative to the rated motor curĆ
rent can be specified in direct mode. With linear motors, this
results in a force (force control).
Operating mode of the SFC−LACI: Profile torque mode"
FHPP Continuous Mode Continuous setpoint specification: Specification of changeĆ
able position values at millisecond frequency (typically
4...10 ms).
Operating mode of the SFC−LACI: FHPP continuous mode"
