Parameter description
Note:
In Freq. ref. 1, the Multi-step option is prior to other frequency reference options. If
the terminal has selected multi-speed and active, the Freq. ref. 1 is determined by
multi-speed no matter what value has F0.03 setup.
In option of Freq. ref. 1+ the Freq. ref. 2, the UP/DOWN digital setting of Freq. ref. 1
will be Up/Down overlapped on Frequency ref.-2. And the F0.06 Up/Down preset
value is invalid.
F0.10 Basic frequency
F0.11 Max frequency
F0.12 Freq, upper limit
F0.13 Freq, lower limit
F0.14 Max output voltage
The basic frequency (Fb) is the Min. output frequency when the drive output the
Max. voltage. Usually, the motor rated frequency can be treated as basic frequency.
The max frequency (Fmax) is the highest frequency that the drive can output.
F0.15 Carrier freq.
This parameter is used to adjust the carrier frequency of the drive. The drive power
ratings and according carrier frequency value range is show as following. The
adjustment of carrier frequency will have influences on motor noise, motor
temperature rising, and drive temperature rising as shown.
