Inadequate heat dissipation during operation can cause the brake resistor to
overheat.
Possible consequences:
The brake resistor is destroyed.
ƒ
The drive is not braked but coasts to a standstill.
ƒ
Protective measures:
Always connect the thermal contact of the brake resistor.
ƒ
Integrate the thermal contact into the overall equipment monitoring
ƒ
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).
