The brake resistor is destroyed.
The drive is not braked but coasts to a standstill.
Always connect the thermal contact of the brake resistor.
Integrate the thermal contact into the overall equipment
monitoring apparatus in such a way that the supply of power to
the standard device is switched off if the brake resistor overheats
(e.g. switch−off by means of mains contactor control).
