Function:
Flux Model shift
Enter the frequency value for shift between two
models for determining motor speed. Choose the
value based on se ttings in pa r. 1-00 Configuration
Mode and par. 1-01 Motor Control Principle.
There are two options: shift between Flux m od el
1 and Flux model 2; or shift between Variable
Current mode and Flux model 2. This parameter
is available for FC 302 only.
This parameter cannot be adjusted while
the motor is running.

closed loop [1] or Torque [2] and par. 1-01 is set to
Flux w/motor fe ed back [3]. With this parameter it
is possible to ma ke an adjustme nt of the shifting
point where FC 302 changes between Flux model 1
and Flux model 2, which is useful in some sensitive
speed and torque control applications.
