Temperature monitoring
The temperature monitoring protects the semiconductor from thermal
overload. If the temperature is too high, the braking and the motor will be
switched off immediately.
Reset after a fault
After rectifying a fault you must either reset manually or the brake unit
goes automatically into “ready for operation”. This status can be set.
