Function
Group 1 is continuously controlled (0 - 100 %), the other groups are switched on and off depending on
the degree of modulation (0 / 100%).
If the modulation level exceeds the switch-on point ON Value Group2, the MODBUS Master switches
on the second group and the speed of the rst group is reduced to an adjustable minimal value nmin
at Group2.
Then the speed of the rst group increases to maximum within the remaining range.
If a third group is programmed up to switch-on point ON Value Group3 etc.
Switch-off point OFF Value Group2 at diminishing speed requirement.
