Group 1: Basic Parameters
 You can set this parameter during operation.
01.00
Maximum Output Frequency (Fmax)
Unit: 0.01
Settings 50.00–400.0 Hz Default: 60.00
 Determines the AC motor drive’s Maximum Output Frequency. All the AC motor drive frequency command
sources (analog inputs 0–10 V and 4–20 mA) are scaled to correspond to the output frequency range.
01.01
Motor Rated Frequency (Fbase) Unit: 0.01
Settings 0.10–400.0 Hz Default: 60.00
 Set this value according to the rated motor frequency as indicated on the motor nameplate. The Maximum
Voltage Frequency determines the V/F curve ratio. For example, if the drive is rated for 460 V
AC
output and
you set the maximum voltage frequency to 60 Hz, the drive maintains a constant ratio of 7.66 V/Hz (460 V / 60
Hz = 7.66 V/Hz). This parameter value must be equal to or greater than the Mid-Point Frequency (Pr.01.03).
01.02
Motor Rated Voltage (Vbase) Unit: 0.1
Settings 230V series 0.1–255.0 V Default: 220.0
460V series 0.1–510.0 V Default: 440.0
 For 230V series, the default is 220.0 V; for 460V series, the default is 440.0 V.
 Sets the maximum output voltage. The setting must be smaller than or equal to the rated motor voltage as
indicated on the motor nameplate.
01.03
Mid-Point Frequency (Fmid) Unit: 0.01
Settings 0.10–400.0Hz Default: 1.50
 Sets the Mid-Point Frequency of any V/F curve. This setting determines the V/F ratio between the Minimum
Frequency and the Mid-Point frequency.
01.04
Mid-Point Voltage (Vmid) Unit: 0.1
Settings 230V series 0.1–255.0 V Default: 10.0
460V series 0.1–510.0 V Default: 20.0
 For 230V series, the default is 10.0 V; for 460V series, the default is 20.0 V.
 Sets the Mid-Point Voltage of any V/F curve. This setting determines the V/F ratio between the Minimum
Frequency and the Mid-Point Frequency.
01.05
Minimum Output Frequency (Fmin) Unit: 0.01
Settings 0.10–400.00 Hz Default: 1.50
 Sets the Minimum Output Frequency of the AC motor drive. This parameter must be equal to or less than the
Mid-Point Frequency (Pr.01.03).
01.06
Minimum Output Voltage (Vmin) Unit: 0.1
Settings 230V series 0.1–255.0 V Default: 10.0
460V series 0.1–510.0 V Default: 20.0
 For 230V series, the default is 10.0 V; for 460V series, the default is 20.0 V.
 Sets the Minimum Output Voltage of the AC motor drive. This parameter must be equal to or less than the Mid-
Point Voltage (Pr.01.04).
 The settings for Pr.01.01–Pr.01.06 must 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 0.1–120.0% Default: 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 equal to 100%.
 The Output Frequency Upper Limit value = (Pr.01.00 * Pr.01.07) /100.
