 Dynamic torque vector control
To get the maximal torque out of a motor, this control calculates the motor torque for the load
applied and uses it to optimize the voltage and current vector output.
Selecting this control automatically enables the auto torque boost and slip compensation function.
This control is effective for improving the system response to external disturbances such as load
fluctuations, and the motor speed control accuracy.
5.7.8 Function code basic settings < 1 >
Driving a Fuji general-purpose motor under the V/f control (F42 = 0 or 2) or dynamic torque vector
control (F42 = 1) requires configuring the following basic function codes.
Select any of the Fuji standard 8-series, HP motor typical model and others with the function code
P99.
Configure the function codes listed below according to the motor ratings and your machinery design
values. For the motor ratings, check the ratings printed on the motor's nameplate. For your
machinery design values, ask system designers about them.
