Carrier Frequency
Selection
Sets the switching frequency of the drive output
transistors. Adjust this setting to reduce audible
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∶ 80 %
Min.: 0 %
Max.: 150 %
C9-01
Switch to the
maximum current
decay time of the
PM open loop
vector control
Adjust the current decay time when I/f switches to
open-loop vector control.
Default∶ 2.0 s
Min.: 0.1 s
Max.: 20.0 s
C9-02
High frequency
switching point of
hysteresis curve
Adjust the frequency of the high frequency
switching point in the hysteresis curve
Default∶ 15.0 Hz
Min.: (C9-03 + 0.1) Hz
Max.: 500.0 Hz
C9-03
Low frequency
switching point of
hysteresis curve
Adjust the frequency of the low frequency
switching point in the hysteresis curve
Default∶ 10.0 Hz
Min.: 0 Hz
Max.: (C9-02 - 0.1) Hz
C9-04
Damping coefficient
of PM speed
estimator
Adjust the rise time of the speed estimator output
signal.
Default∶ 0.7
Min.: 0
Max.: 2.0
C9-05
The natural
frequency of the
PM speed estimator
Adjust the response bandwidth of the speed
estimator output signal.
Default∶ 60
Min.: 0
Max.: 200
C9-06
PM angle estimator
error
Monitor the amount of error in the non-sensing
vector control estimation angle
