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%.

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.

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.
