4.7.4 Servo sensitivity (SV)
The eroding parameter Servo Sensitivity SV in the erosion table is evaluated directly by the control.
Its function is to adjust the gap control characteristic and thus the reaction speed to the gap signal.
SV is expressed as a percentage (0–99%) of the original characteristic gradients.
