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 first group is reduced to an adjustable minimal value “nmin
at Group2”.
Then the speed of the first 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.
