4-28

Revision July 2008, EG03, SW V1.06

01 - 04

Mid-point Voltage

Settings

0.2V~510.0V

Factory Setting: 11.0

This parameter sets the Mid-point Voltage of the V/F curve.

This parameter must meet the following argument. Pr.1-02 >= Pr.1-04 >= Pr.1-06.

01 - 05

Minimum Output Frequency

Settings

0.10~20.00

Hz

Factory Setting: 3.00

This parameter sets the Minimum Output Frequency of the AC drive. This parameter must be

lower than or equal to the Mid-point frequency.

01 - 06

Minimum Output Voltage

Settings

0.2V~100.0V

Factory Setting: 11.0

This parameter sets the Minimum Output Voltage of the AC Drive. The parameter must be

lower than or equal to the Mid-point Voltage.

01 - 07

Upper Bound Frequency

Settings

0.00~160.00 Hz

Factory Setting: 60.00

This parameter will limit the maximum output frequency of AC drive. If slip compensation

(Pr.07-02~07-05) or feedback control (Pr.10-00~10-09) are enabled, the output frequency of

AC drive may exceed the Master Frequency Command, but it will continue to be limited by this

parameter setting.

01 - 08

Lower Bound Frequency

Settings

0.00~160.00

Hz

Factory Setting: 0.00

This parameter will limit the minimum output frequency. Any Master Frequency Command

below Pr.1-08, will result in an output equal to Pr.1-08.

Upon a start command, the drive will accelerate from Pr.1-05 Minimum Output Frequency to

the Master Frequency Command point.
