Continuous operationThe 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 operat-ing temperatures.
Overload rangeThe 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.
