Magnetic Field
Weakening Level Set the MxC output voltage when the
field weakening command is input.
It is enabled when the field weakening
command is set for a multi-function
input.
Set the level as a percentage taking the
voltage set in the V/f pattern as 100%.

Magnetic Field
Frequency Set the lower limit in hertz of the fre-
quency range where field control is valid.
The field weakening command is valid
only at frequencies above this setting and
only when the speed is in agreement with
the current speed reference.

Magnetic Field
Forcing Limit Set the excitation current reference’s
upper limit for field forcing. Set the limit
as a percentage, taking the motor’s no-
load current as 100%. Enabled for opera-
tion other than DC excitation.
Usually, there is no need to change this
setting.
