[Reduce Ilmt Sel]
Enables the use of a reduced current limit when in overload.
“Disabled” = The Converter current limit is always the value in parameter 100 -
[Active I Lmt].
“Enabled” = The Converter current limit will switch to the value set by parameter
101 - [Active OL I Lmt] when in overload.

[Voltage Loop Sel]
Selects the operation of the voltage loop.
“Optimize Ref” = Vdc reference is calculated to minimize switching losses,
based on the measured AC Line voltage and the minimum voltage required by
the Inverter.
“Manual Ref” = The value set by parameter 060 - [DcLink Reference] is used for
Vdc reference.
“Regen Only” = Reserved for future.
“Open Loop” = The Converter outputs a sinusoidal voltage synchronized to the
AC line with an amplitude set by parameter 063 - [Modulation Index]. This
feature requires a password to operate.
