4-22 Revision May 2008, ME14, SW V3.04
Pr.06
Mid-Point Frequency
Unit: 0.1Hz
Settings 0.10 to 400.0Hz Factory Setting: 1.50
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. Setting of this
parameter must be equal to or greater than Minimum Output Frequency (Pr.08) and
equal to or less than Maximum Voltage Frequency (Pr.04).
Pr.07
Mid-Point Voltage
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 10.0
460V series 0.1 to 510.0V Factory Setting: 20.0
575V series 0.1 to 637.0V Factory Setting: 26.1
The parameter sets the Mid-Point Voltage of any V/F curve. With this setting, the V/F ratio
between Minimum Frequency and Mid-Point Frequency can be determined. Setting of this
parameter must be equal to or greater than Minimum Output Voltage (Pr.09) and equal
to or less than Maximum Output Voltage (Pr.05).
Pr.08
Minimum Output Frequency
Unit: 0.1Hz
Settings 0.10 to 20.00Hz Factory Setting: 1.50
The parameter sets the Minimum Output Frequency of the AC drive. Setting of this
parameter must be equal to or less than Mid-Point Frequency (Pr.06).
Pr.09
Minimum Output Voltage
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 10.0
460V series 0.1 to 510.0V Factory Setting: 20.0
575V series 0.1 to 637.0V Factory Setting: 26.1
This parameter sets the Minimum Output Voltage of the AC drive. Setting of this parameter
must be equal to or less than Mid-Point Voltage (Pr.07).
