Range: 10.0 to 400.0 Hz Default: 60.0
Unit: 0.1 Hz
This value should be set according to the rated frequency of
the motor as indicated on the motor nameplate. Motor
Nameplate Frequency determines the volts/hertz ratio.
For example: if the drive is rated for 460V AC output and the
Motor Nameplate Frequency is set to 60 Hz, the drive will
maintain a constant ratio of 7.66 v/Hz.
The setting value must
equal to or greater than the Mid-Point Frequency (50.07).
20.02 Range: 115V series 0.1 to 255V Default: 230.0
Motor Nameplate
Voltage
Range: 230V series 0.1 to 255V Default: 230.0
Range: 460V series 0.1 to 510V Default: 460.0
Range: 575V series 0.1 to 637V Default: 575.0
This parameter determines the Motor Nameplate Voltage of
the AC drive. The Motor Nameplate Voltage setting must be
smaller than or equal to the rated voltage of the motor as
indicated on the motor nameplate.
The setting value must
equal to or greater than the Mid-Point Voltage (50.08).
