5.13.6 Over load protection
With this function it’s possible to select between Current,
Torque and Power what is used for over load protection.
Over Load in based on internal counter that in increased
when input value is above 105 % level and decreased when
below 105 % level, increase and decrease is happening
every 100 ms. Tripping is made when over load counter
value is over 10 000.
With parameters it can be defined what is increase (Over
load maximum step) at maximum defined input level (Over
Load Maximum Input). These points defines slope for the
function. e.g. if input value is middle of 105 % and Over
Load Maximum Input values counter is increase half of the
Over Load Maximum step.
