3.2.5.2 Note to the function
In the example above the locking of the line contactor K1 is interrupted in case of overheating
of the braking resistor. The line contactor drops and switches off the mains voltage. The au-
xiliary contacts 13/14 open the error linkage circuit at terminals I1/COM and release an error.
The modulation is switched off. Thus the drive in generatoric operation does not regenerate
further energy into the DC link circuit.
