Application as a global inverter is enabled by displays in Japanese, English, French, German, Italian,
Spanish, or Portuguese.
H Low-speed Rotation Inconsistencies Greatly Reduced
Improvements in the current detector for vector control and in the responsiveness of current control
have greatly reduced torque ripple. This greatly reduces the low-speed inconsistencies for the 3G3FV
Series.
H Better Motor Speed Control Accuracy (Parameter C3-06)
Previously the motor speed control accuracy for vector control was greatly reduced when the limit of
Inverter's voltage output was approached (a voltage greater than that of the input power supply cannot
be output). If the new output voltage control method is used, the output voltage will be controlled so that
the limit will not be reached, thus maintaining speed accuracy. The linear characteristic of torque control
has also been improved.
Note The current may increase by about 10% when this function is used. Be sure to select an Inverter
with ample output current capacity.
H Improved Motor Parameter Autotuning
A new method has been added for autotuning to produce greater accuracy.
H Improved PID Control
Additions have been made to PID control to increase the range of possible applications.
PID Control Reverse Characteristics (Parameter b5-09)
Previously, only positive characteristic PID control, in which the feedback value increases when the
Inverter's output frequency increases, was possible. In addition to this, reverse characteristic PID con-
trol is now possible, in which the feedback value decreases when the Inverter's output frequency
increases.
Frequency Reference + PID Control (Parameters b5-01 and b5-10)
A control method using the frequency reference and PID control has been added between the previous
frequency reference or PID control. This is ideal for applications in which the target speed is set, but fine
adjustments need to be made with PID control (such as tension control).
Reverse Motor Control for PID Control (Parameter b5-11)
Motor rotation in only one direction was possible for previous PID control, but a reverse control setting
has been added to produce rotation in the reverse direction when the PID control result is negative.
