Three different control types can be set.
“Freq+speed contr”:
If the frequency was determined via automatic search, the control
unit then regulates the frequency automatically when the
superstructure is loaded.
The feed speed set is then also maintained if the loads are
changed.
This option can only be selected after the automatic frequency
search. If the frequency is set manually, the control type “Only
speed contr.” is then is set automatically here.
“Only speed contr.”:
If this control type is already set in the menu, the control unit then
only regulates the speed when loading the drive. The frequency
remains unchanged.
“Quiet / Contr off”:
If this control type is set in the menu, then the device works with a
sinusoidal frequency at the output.
The drive is significantly quieter and light parts no longer jump in
the superstructure of the drive.
The maximum output current should be limited to 5 A as heat
generation is higher here.
An automatic readjustment in the event of higher loads is not
possible here.
