2.1.1 Typical short-term overload limits
The maximum percentage overload limit changes depending on the
selected motor.
Variations in motor rated current will result in changes in the maximum
possible overload as detailed in the Mentor MP Advanced User Guide.
Figure 2-1 can be used to determine the maximum overload duration
available for overloads between 100% and 150%. For example the
maximum overload available for a period of 60 seconds is 124%.
Figure 2-1 Maximum overload duration available
Overload of 150% for 30s is available up to a maximum of 10 repetitions
per hour.
