Overload message OL
The digital output configured as OL is activated when a freely
selectable motor current is exceeded. The OL output is active as
long as the motor current is higher than this threshold.
X If you want to configure a programmable digital output as OL,
you must set the current under PNU C41, at which the OL signal
activates when it has been exceeded.
X Then, program one or more of the digital outputs 11 or 12 as
the OL output, by setting the value 03 under PNU C21 or C22.
