n [rpm]
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.
