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