CH 5-2 Group 1: Basic Parameters

1 – 00 Maximum Output Frequency (Fo. max) Factory Setting: d 60.0

Settings d 50.0 to d 400 Hz Unit: 0.1Hz

& This parameter determines the AC drive’s Maximum Output Frequency. All

the AC drive analog inputs (0 to +10V, 4 to 20mA) are scaled to correspond

to the output frequency range.

1 - 01 Maximum Voltage Frequency Factory Setting: d 60.0

Settings d 10.0 to d 400Hz Unit: 0.1Hz

& This value should be set according to rated frequency of the motor as

indicated on the motor nameplate. Maximum Voltage Frequency determines

the volts per hertz 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. The setting value must be greater than or equal

to the middle freq. setting (Pr.1-03).

1 - 02 Max. Output Voltage (Vmax) Factory Setting: d 220*

Settings d 2.0 to d 255V* Unit: 0.1V*

*Twice value for 460V class

& This parameter determines the Maximum Output Voltage of the AC 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. The setting

value must be greater than or equal to the Mid-Point Voltage (Pr.1-04).
