DETAILED PARAMETER DESCRIPTION
6.3.10 - P15 -
Immediate
undercurrent
Time(s)
Through this parameter is determined the maximum
time that the load can operate with undercurrent,
as set in P14. Typical application for this function is
in pumping systems that benefit when they are dry
operated.

6.3.11 - P22 - Rated
current of the
Soft-Starter (A)
It is function is to adjust the Software to certain
conditions of the hardware, being used as base of the
following functions: starting current limitation (P11);
immediate overcurrent (P12) at duty; undercurrent at
duty (P14) and thermal overload protection of the motor.
6.3.9 - P13 - Immediate
Overcurrent
Time(s)
This parameter determines the maximum time that the
load can operate with overcurrent, as set in P12.
