Figure8-84 Factory setting of the 󹪞ow characteristic
To set the characteristic, you require the following data from the machine manufacturer for
each speed interpolation point:
• The 󹪞ow rate of the 󹪞uid-󹪞ow machine associated with the 5 selected converter speeds
• At constant speed, the power drawn which is associated with the 5 󹪞ow rates corresponds to
the line frequency and mechanical throttling of the 󹪞ow rate.
