Chapter 6 Description of parameter setting
Introduction: P300=2 AVI minimum voltage input: 2V (inverter regards signals
below 2V as invalid signals);
P301=10 AVI maximum voltage input: 10V (signals over 10V are regarded and
handled as 10V);
P310=50 Analogue low-end frequency: 50Hz;
P311=1 Analogue low-end direction: 1 (reverse);
P312=50 Analogue high-end frequency: 50Hz;
P313=0 Analogue high-end direction: 0 (Forward);
P314=1 Analogue reverse selection: 1 (negative bias voltage can be reversed).
Attention: In various curves, switching instructions of forward and reverse
remain effective, when forward and reverse are switched, the curve will be
reversed, and the diagram of curve is as follows:
