Descriptions of
Parameter Settings
50.04
Maximum Output
Frequency
Range: 50.0 to 400.0 Hz Default: 60
Unit: 0.1 Hz
This parameter determines the AC drive’s Maximum Output
Frequency. All the AC drive accelerations and decelerations
are scaled to correspond to this maximum output frequency.
50.05
Motor Nameplate
Frequency
Range: 10.0 to 400.0 Hz Default: 60
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
Maximum Voltage 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).
50.06 Range: 115V series 0.1 to 255.0V Default: 230.0
Motor Nameplate
Voltage
Range: 230V series 0.1 to 255.0V Default: 230.0
Range: 460V series 0.1 to 510.0V Default: 460.0
Range: 575V series 0.1 to 637.0V 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).
50.07
Mid-Point Output
Frequency
Range: 0.1 to 400.0 Hz Default: 1.5
Unit: 0.1 Hz
The parameter sets the Mid-Point Frequency of V/F curve.
With this setting, the V/F ratio between Minimum Frequency
and Mid-Point frequency can be determined.
This parameter
must be equal to or greater than Minimum Output Frequency
(50.09) and equal to or less than Motor Nameplate Frequency
(50.05).
During Sensorless Vector this parameter is disabled.
