S3.10
Droop control Factory Default 0.00 Hz
Setting range 0.00 − 10.00 Hz Minimum unit 0.01 Hz
Used to change the decrease value of the output frequency.
This function is suitable for circumstances where multiple converters are
used to drive the same load And allows even of output power distribution.
●
When a converter is subject a too high load, the converter will automati‐
cally reduce its output frequency to reduce the load according to the pa‐
rameter setting.
Change the value gradually in case of adjustment. The relationship be‐
tween the load and output frequency is illustrated in fig. 7-30 "Droop
control" on page 109 .
