U1.1 Menue: Tuning Speed Loop
Stable parameters are calculated bases
on the system data; and can be called up with F5.
Sometimes it is recommanded to make further manual
tuning.
Rated values can be sourced either digital by the internal
generator or analog by using +/-10V at X10.5/18.
ATTENTION !
Too hard tuning will cause current-
ripple and high power-dissipation.
