Monitoring types
The converter monitors its temperature using the following monitoring types:
• I
• Measuring the chip temperature of the converter (alarm A05006, fault F30024)
• Measuring the heat sink temperature of the converter (alarm A05000, fault F30004)
Function description
Overload response for p0290 = 0
The converter responds depending on the control mode that has been set:
• In vector control, the converter reduces the output current.
• In U/f control, the converter reduces the speed.
Once the overload condition has been removed, the converter re-enables the output current
or speed.
If the measure cannot prevent a converter thermal overload, then the converter switches off
the motor with fault F30024.
Overload response for p0290 = 1
The converter immediately switches off the motor with fault F30024.
Overload response for p0290 = 2
We recommend this setting for drives with square-law torque characteristic, e.g. fans.
