*1) The result of automatic calculation can be checked with the PC Loader.
*2) 1 s or less reference values are assumed to be 1 s for easy tuning.
The frequency of a reciprocal motion is 25 cycles maximum, and that of a single-direction motion is 50
cycles maximum.
Details of tuning
Up to 50 easy tuning cycles are repeated while auto tuning gain 1 is automatically adjusted in the
range from 5 to 30.
Details of completion of action
The action completion method includes three profiles: normal completion, interruption by user, and
faulty termination. Each profile is described below.
Faulty termination
Normal completion Interruption by user

Auto tuning gain 1 (range
between 5 and 30) is
automatically adjusted to the
best value. Auto tuning gain 1 at
the start of
operation is
restored. Auto tuning gain 1 at
the start of
operation is
restored. Auto tuning gain 1
automatically changes
to the one that will
suppress resonance
(re-adjustment is
