The digital inverter enabling output is activated in each case in which the analogue output has a value other than 0%.
The above drawing represents only the nominal case in which the cut-off hysteresis is enabled at the minimum.
Parameters CP08 (enable minimum cut-off) and CP09 (enable saturation cut-off) activate or deactivate the cut-off
function. Note that, if the minimum cut-off is disabled, the speed of the inverter compressor goes from 0 to the
minimum speed when the regulation probe reaches the set point from "below". If the regulation probe reaches the
set point from “above”, the speed will go from minimum speed to 0. Similarly if the saturation cut-off is disabled, the
speed of the inverter compressor goes from continuous regulation to maximum speed when the regulation probe
reaches Set point+Proportional Band from "below”. If the regulation probe reaches Setpoint+Proportional Band from
"above" there will be continuous regulation between maximum and minimum speed.
Regulation probe error: the inverter compressor will be piloted at the speed set by parameter CP21.
