5.4.12 SetSpeedSetPoint
Function: Changes the "Speed Set Point" value. This value can be changed the range from 18,500 to
36,500 rpm. The threshold value of the illumination pattern of the "ROTATION" LED is fixed. It is not
changed even if the setting value of the rotational speed is changed.
CAUTION
There is an endurance limit of setting changes (no more than 24 times per day for about ten years).
If this limit is exceeded, it not only may become impossible to change the setting but can also cause
pump failure. Do not make setting changes in excess of this endurance limit.
