Mode 3:
MDI
(Point-to-point
positioning)
Mode 2:
Homing procedure
(approaching the reference
point, only with incremental
position encoders, e.g. Re-
solvers, ERN encoders,
pulse encoders)
Mode 1:
Set-up
(position controlled inching
taking into account the soft-
ware limit switch)
Mode 4:
Control
(speed-controlling inching
without taking into account
the software limit switch)

Sampling times
<1> Sampling time for the positioning
modes:
Recommended: U953.32 = 4
<2> Sampling time for synchronism:
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
input/output signals; only permitted if
positioning modes are deactived
(i.e. if U953.32 = 20)
<3> Sampling time for virtual...
... and real master axis:
The virtual and real master axes are
independent free blocks.
