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.
