n [rpm]
Continuous operation The drive can be operated with a speed controller and, taking account of the given thermal resistance (fig. 17 and 18) at an ambient temperature of 25°C, does not exceed the maximum permissible operating temperatures. Overload range The drive reaches these operating points. Speed may vary from the set value. The overload protection shuts down the drive in the event of sustained overload.
