Parameter Unit Description / Notes
 The undercurrent and the overcurrent parameters are set as per-
centage of the nominal motor current (P401).
 P610 sets the immediate undercurrent level at which the motor can
operatewithoutproblemsduringthetimeadjustedinP611.Afterthis
time has elapsed the Soft-Starter is disabled indicating undercurrent
fault. This function is generally used in applications with hydraulic
pumps which cannot be operated without a load.
P612 sets the maximum overcurrent levels that the motor or Soft-
-Starter allows for the time set at P613, after which the Soft-Starter
isswitchedO󰀨andtheOvercurrentErrorisdisplayed.
For programming examples refer to the item 7.2.2.
NOTE!
These Functions are only active after the motor start and after
full voltage level has been reached.

 The current imbalance values are set as percentage of the nominal
motor current (P401).
P614setsthemaximumcurrentdi󰀨erencebetweenthethreemotor
phases at which the motor can operate without problems, for the
time set at P615. If these values are exceeded, the Soft-Starter is

 These settings also activate the phase fault protection during the
starting process and during operation at full voltage.
NOTE!
This function is actuated only after motor start and after full
voltage level has been reached.
