Overload signal OL, OL2
The digital output configured as OL or OL2 is activated when a
freely selectable motor current is exceeded. The OL/OL2 output is
active as long as the motor current is higher than this threshold.
X If you configure a programmable digital output as OL, you must,
under PNU C041, enter the current at which, when exceeded,
the OL signal is activated.
X To configure a programmable digital output as OL2, define the
current under PNU C111 at which, when exceeded, the OL2
signal is activated.
X Then, program one of the digital outputs 11 to 15 as OL output
by setting the corresponding PNU (C021 to C025) to 03.
X Then, program one of the digital outputs 11 to 15 as OL2 output
by setting the corresponding PNU (C021 to C025) to 26.
By default, OL is assigned to digital output 13.
