U< E Value exceeds limit value
Setting undervoltage V< as %
You can use this parameter to set the limit value as a relative value (%). This
limit value refers to the desired value you have set. If you want to use the set
relative value as the limit value, go to
Absolute limit values and activate
the Off selection.
To set the limit value for undervoltage V<, proceed as follows:
