NOTICE
Thermal damage to temperature-sensitive parts
Some parts of the electrical motor enclosure can reach temperatures that exceed 100 °C.
If temperature-sensitive parts, for instance electric cables or electronic components, come
into contact with hot surfaces then these parts can be damaged.
•
Ensure that no temperature-sensitive parts come into contact with hot surfaces.
NOTICE
Motor destroyed as a result of overheating
The motor may overheat without temperature protection and be destroyed.
•
Check whether the temperature protection is effective before switching on the DC link
voltage for the first time!
NOTICE
Demagnetizing the permanent magnets
If, while the torque motor is operational, the rotor exceeds the maximum temperature of
120 °C, then there is a risk that the permanent magnets will be demagnetized.
Especially high temperatures are to some extent locally possible as a result of an even
current loading. Operating states with uneven current loading include standstill or operation
with short, cyclic rotary motion.
• When commissioning the system for the first time, make the appropriate checks so that
it is ensured that the rotor does not exceed the maximum temperature of 120 °C.
