Programmable relay outputs
K11 to K34

Overload signal (OL)
The relay 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 To configure a programmable relay output as OL, define the
current under PNU C041 at which, when exceeded, the OL
signal is activated.
X Then, program one of the relay outputs K23-K24 or K33-K34 as
OL output by entering the value 03 under PNU C021 or C022 or
in PNU C026 for signalling relay contacts K11K12.
