Protection and Features
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a
predefined level. An overload temperature cannot be reset until the temperature of the heatsink is below the
values stated in the tables on the following pages (Guideline - these temperatures may vary for different power
sizes, frame sizes, enclosure ratings etc.).
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the DC voltage ensures that the frequency converter trips if the DC circuit voltage is too low or too
high.
•
The frequency converter constantly checks for critical levels of internal temperature, load current, and the DC
voltage. As a response to a critical level, the frequency converter can adjust the switching frequency and/ or
change the switching pattern to ensure the performance of the frequency converter.

1) The typical overload percentage is 150. The P1M2 to P1M6 overload percentage is 175.
2) The efficiency is estimated at the nominal load condition. It is expected to be within
±
15%. If the switching frequency is increased, the power
loss rises.
