The range of values the inverter output may assume is comprised of between 0 and 100 percentage
points, with two decimal places.
By enabling the inverter, for a given number of compressors, one step is lost, which will be replaced
by regulation with inverter on the first compressor.
Below is given an example of how to change regulation with the presence of an inverter.
6.3.4 Neutral zone regulation with inverter
This type of control introduces inverter control to normal neutral zone control, and in order to do
this it is essential to set several parameters relating to the inverter device it is intended to use, in
addition to enabling its use. The parameters in question are the following:
⋅
Inverter enabling
⋅
Minimum inverter value (MinI)
⋅
Inverter time (IT)
⋅
SpeedUp time
⋅
neutral zone suction setPoint
Regulation varies according to the zone (neutral, on or off) in which the regulator is located.
