Group 1: Basic Parameters
1-00
Maximum Output Frequency (Fmax) Unit: 0.1
Settings d50.0 to d400 Hz Factory Setting: d60.0
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.
1-01 Maximum Voltage Frequency (Fbase) Unit: 0.1
Settings d10.0 to d400 Hz Factory Setting: d60.0
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.1-03).
1-02 Maximum Output Voltage (Vmax) Unit: 0.1
Settings 115V/230V series d2.0 to d255V Factory Setting: 220.0
460V series d4.0 to d510V 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.1-04).
1-03 Mid-Point Frequency (Fmid) Unit: 0.1
Settings d1.0 to d400Hz Factory Setting: d1.0
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.1-05) and equal to or less
than Maximum Voltage Frequency (Pr.1-01).
1-04 Mid-Point Voltage (Vmid) Unit: 0.1
Settings 115V/230V series d2.0 to d255V Factory Setting: d12.0
460V series d4.0 to d510V Factory Setting: d24.0
