Operating modes
[MODE_IN]
<1>
Mode 1:
. . Set-up . .
(position controlled inching
. .
taking into account the soft-
ware limit switch)
[819]
Mode 2:
Homing procedure
. .
(approaching the reference
. .
. .
point, only with incremental
position encoders, e.g. Re-
solvers, ERN encoders,
pulse encoders)
[821]
Mode 3:
. .
. .
MDI
. .
(Point-to-point
positioning)
[823]
Mode 4:
. .
Control
. . . .
(speed-controlling inching
without taking into account
the software limit switch) [825]
Modes 5 and 6:
. . . .
Automatic
. .
(Automatic run-through of
traversing programs)
[826...828]
Mode 11:
. .
Synchronism

Sampling times
<1> Sampling time for the positioning
modes:
U953.32 = ___(20)
Recommended: U953.32 = 4
<2> Sampling time for synchronism:
U953.33 = ___(20)
U953.33 = 20 => Synchronism as a
positioning mode inserted in the
sampling time determined by U953.32
U953.33 < 20 => Synchronism operates
as autonomous free block with its own
KK0315
input/output signals; only permitted if
positioning modes are deactived
B0351...362
(i.e. if U953.32 = 20)
<3> Sampling time for virtual...
U953.34 = ___(20)
B0311...316
... and real master axis:
U953.31 = ___(20)
The virtual and real master axes are
independent free blocks.
