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 400 Hz 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 230*

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).
