noise and leakage current.
2: 2.0 kHz
4: 4.0 kHz
8: 8.0 kHz
12: 12.0 kHz
16: 16.0 kHz
Default: Determined by
A1-02 and o2-03.
Range: 2 to 16
C9: PM motor speed estimator
C9-00
Operating current
command in I/f
control state Sets the I/f running current command (%)
depending on the load, so that the rated current
of the inverter is 100%. Default
