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
