Field weak-
ening level
Sets the inverter output volt-
age when the field weakening
command is input at a digital
input.
Sets the voltage level as a per-
centage taking the voltage set
by the V/f pattern as 100%.

Field weak-
ening fre-
quency limit
Sets the lower limit of the fre-
quency range where field con-
trol is valid.
The field weakening com-
mand is accepted only at fre-
quencies above this setting
and only when the speed is in
agreement with the current
speed reference.

Limit
Sets the upper limit for the
excitation current applied by
the field forcing function.
A setting of 100% is equal to
the motor no-load current.
Field forcing is active during
