Description
Defines the first voltage point of the custom U/f curve at the
frequency defined by parameter
See section Custom U/f ratio
V Voltage
Defines the first frequency point of the custom U/f curve.
Frequency
Defines the second voltage point of the custom U/f curve at
the frequency defined by parameter
F2. See section Custom U/f ratio
V Voltage
Defines the second frequency point of the custom U/f curve. 20.0 Hz
Frequency
Defines the third voltage point of the custom U/f curve at the
frequency defined by parameter
See section Custom U/f ratio
V Voltage
Defines the third frequency point of the custom U/f curve.
Frequency
Defines the fourth voltage point of the custom U/f curve at
the frequency defined by parameter
F4. See section Custom U/f ratio
V Voltage
Defines the fourth frequency point of the custom U/f curve.
Frequency
Defines the voltage of the U/f curve when frequency is equal
to or exceeds the motor nominal frequency
NOM FREQ). See section
V Voltage
Enables or disables the DC voltage stabilizer. The DC
stabilizer is used to prevent possible voltage oscillations in
the drive DC bus caused by motor load or weak supply
network. In case of voltage variation, the drive tunes the
frequency reference to stabilize the DC bus voltage and
therefore the load torque oscillation.
