Depending on the type of device ordered and the device connections, some of the operational measured
values listed below may not be available.

In addition, the following may be available:
•
Θ/Θ thermal measured value of overload protection value for stator in % of the trip initiating over-

The calculation of the operational measured values is also performed during a fault. The values are updated in
intervals of > 0.3 s and < 1 s.

Transfer of Measured Values

Measured values can be transferred via the interfaces to a central control and storage unit.
The measuring range in which these values are transmitted depend on the protocol and, if necessary, addi-
tional settings.
