Delta Electronics VFD-G manual 01 04 Mid-point Voltage Settings 2V~510.0V

Chapter 4 Parameters

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 HzFactory 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~100.0VFactory 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 HzFactory 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.
