Group 1: Basic Parameters
01.00
Maximum Output Frequency (Fmax)
Unit: 0.01
Settings 50.00 to 599.0 Hz Factory Setting: 60.00
This parameter determines the AC motor drive’s Maximum Output Frequency. All the AC motor drive
frequency command sources (analog inputs 0 to +10V and 4 to 20mA) are scaled to correspond to the output
frequency range.
01.01
Maximum Voltage Frequency (Fbase) Unit: 0.01
Settings 0.10 to 599.0Hz Factory Setting: 60.00
This value should be set according to the rated frequency of the motor as indicated on the motor nameplate.
Maximum Voltage Frequency determines the v/f curve ratio. For example, if the drive is rated for 460 VAC
output and the Maximum Voltage Frequency is set to 60Hz, the drive will maintain a constant ratio of 7.66
V/Hz (460V/60Hz=7.66V/Hz). This parameter value must be equal to or greater than the Mid-Point Frequency
(Pr.01.03).
01.02
Maximum Output Voltage (Vmax) Unit: 0.1
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 220.0
460V series 0.1 to 510.0V Factory Setting: 440.0
This parameter determines the Maximum Output Voltage of the AC motor drive. The Maximum Output
Voltage setting must be smaller than or equal to the rated voltage of the motor as indicated on the motor
nameplate. This parameter value must be equal to or greater than the Mid-Point Voltage (Pr.01.04).
01.03
Mid-Point Frequency (Fmid) Unit: 0.01
Settings 0.10 to 599.0Hz Factory Setting: 1.50
This parameter sets the Mid-Point Frequency of the 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 (Pr.01.05) and equal to or less than Maximum Voltage Frequency (Pr.01.01).
01.04
Mid-Point Voltage (Vmid) Unit: 0.1
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 10.0
460V series 0.1 to 510.0V Factory Setting: 20.0
This 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. This parameter must be equal to or greater than
Minimum Output Voltage (Pr.01.06) and equal to or less than Maximum Output Voltage (Pr.01.02).
01.05
Minimum Output Frequency (Fmin) Unit: 0.01
Settings 0.10 to 599.0Hz Factory Setting: 1.50
This parameter sets the Minimum Output Frequency of the AC motor drive. This parameter must be equal to
or less than Mid-Point Frequency (Pr.01.03).
01.06
Minimum Output Voltage (Vmin) Unit: 0.1
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 10.0
460V series 0.1 to 510.0V Factory Setting: 20.0
This parameter sets the Minimum Output Voltage of the AC motor drive. This parameter must be equal to or
less than Mid-Point Voltage (Pr.01.04).
The settings of Pr.01.01 to Pr.01.06 have to meet the condition of Pr.01.02 ≥ Pr.01.04 ≥ Pr.01.06 and
Pr.01.01 ≥ Pr.01.03 ≥ Pr.01.05.
01.07
Output Frequency Upper Limit Unit: 0.1
Settings 0.1 to 120.0% Factory Setting: 110.0
This parameter must be equal to or greater than the Output Frequency Lower Limit (Pr.01.08). The Maximum
Output Frequency (Pr.01.00) is regarded as 100%.
