Delta Electronics VFD-E manual 01.04, 01.05, 01.06, 01.07

			Chapter 4 Parameters
01.04	Mid-Point Voltage (Vmid) (Motor 0)			Unit: 0.1
	Settings 115V/230V series	0.1 to 255.0V		Factory Setting: 10.0
	460V series	0.1 to 510.0V		Factory Setting: 20.0

This parameter sets the Mid-Point Voltage of any V/f curve. With this setting, the V/f ratio between Minimum Frequency and Mid-Point Frequency can be determined. This parameter must be equal to or greater than Minimum Output Voltage (Pr.01.06) and equal to or less than Maximum Output Voltage (Pr.01.02).

This setting should be greater than Pr.01.06.

01.05	Minimum Output Frequency (Fmin) (Motor 0)	Unit: 0.01
	Settings 0.10 to 600.0Hz	Factory Setting: 1.50

This parameter sets the Minimum Output Frequency of the AC motor drive. This parameter must be equal to or less than Mid-Point Frequency (Pr.01.03).

The settings of 01.03, 01.04, and 01.06 are invalid in Vector Control mode.

01.06	Minimum Output Voltage (Vmin) (Motor 0)			Unit: 0.1
	Settings 115V/230V series		0.1 to 255.0V	Factory Setting: 10.0
		460V series	0.1 to 510.0V	Factory Setting: 20.0

This parameter sets the Minimum Output Voltage of the AC motor drive. This parameter must be equal to or less than Mid-Point Voltage (Pr.01.04).

The settings of Pr.01.01 to Pr.01.06 have to meet the condition of Pr.01.02 ≥ Pr.01.04 ≥ Pr.01.06 and Pr.01.01 ≥ Pr.01.03 ≥ Pr.01.05.

In vector control mode (Pr.00.10 is set to 1), Pr.01.03, Pr.01.04 and Pr.01.06 are disabled.

01.07	Output Frequency Upper Limit	Unit: 0.1
	Settings 0.1 to 120.0%	Factory Setting: 110.0

This parameter must be equal to or greater than the Output Frequency Lower Limit (Pr.01.08). The Maximum Output Frequency (Pr.01.00) is regarded as 100%.

Output Frequency Upper Limit value = (Pr.01.00 * Pr.01.07)/100.
