Pr.03

Maximum Output Frequency

Factory Setting: 60.00

Settings 50.00 to 400.0 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.

Pr.04

Maximum Voltage Frequency (Base Frequency)

Factory Setting: 60.00

Settings 10.00

400.0Hz

Unit:

0.1Hz

This parameter should be set according to the rated frequency as indicated in the motor

nameplate. Pr.04 and Pr.03 determine 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.

Setting of Pr.04 must be

equal to or greater than setting of Mid-Point Frequency (Pr.06).

Pr.05

Maximum Output Voltage (Vmax)

Settings
