Features of the 8600 series
variant dancer-Position control
In addition to numerous
Standard
functions, this variant offers
various functions
which
are required for a dancer-Position control
used for winding applications.
Another possibility is to activate a torque control.
For more detailed information
about
the
special
functions see
chapters
9 and
10.
