5.3.3 C codes (Control functions)
C01 to C04
Jump frequency 1, 2 and 3, Jump frequency (Skip width)
These function codes enable the inverter to jump over three different points on the output frequency in order to skip
resonance caused by the motor speed and natural frequency of the driven machinery (load).
While increasing the reference frequency, the moment the reference frequency reaches the bottom of the jump
frequency band, the inverter keeps the output at that bottom frequency. When the reference frequency exceeds
the upper limit of the jump frequency band, the internal reference frequency takes on the value of the reference
frequency. When decreasing the reference frequency, the situation will be reversed. Refer to the left figure
below.
When more than two jump frequency bands overlap, the inverter actually takes the lowest frequency within the
overlapped bands as the bottom frequency and the highest as the upper limit. Refer to the right figure below.
Jump frequency 1, 2 and 3 (C01, C02 and C03)
Specify the center of the jump frequency band.
Data setting range: 0.0 to 500.0 (Hz) (Setting to 0.0 results in no jump frequency band.)
Jump frequency skip width (C04)
Specify the jump frequency skip width.
Data setting range: 0.0 to 30.0 (Hz) (Setting to 0.0 results in no jump frequency band.)
