12.3 Suppression of speeds
Suppression of up to three speed ranges.
Under certain circumstances, it is possible to prevent disturbing noises that can arise at certain speeds due to
resonances.
In voltage control devices and control modules, this can only be indirectly performed via the internal level control.
Factory setting no suppression activ = “OFF“
for operation with suppression switch to “ON“
Einstellung für Bereich „1min“
Einstellung für Bereich „1max“
Identical procedures for suppression
2 and suppression 3, as far as desired.
