Mid-Point Voltage; Minimum Output Frequency; Minimum Output Voltage; Upper Bound Frequency - Delta Electronics AC Drive VFD-F Series User Manual

01 - 04

Mid-point Voltage

Settings
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
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
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
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
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.
The Lower Bound Frequency setting must be smaller than the Dwell Frequency
(Pr.11-08>=01-08). If lower bound frequency setting is greater than the Dwell Frequency,
the AC drive will equalize the two settings to the Lower Bound point.
