OVERLOAD fUNCTION

3.3 Overload function

Valid for drive controllers from firmware version 2.2.0.43.

The overload duration achievable in practice depends essentially on the cooling condi-

tions. The overload protection of the drive controller is triggered by the following causes:

•

The OL function protects the drive controller against permanent overload. Depending on

the cooling, long-term operation in the overload range can lead to the "ERROR overheat

powermodules", which trips the drive before the OL function responds.

The following graphic shows the tripping time as a function of the respective constant

overload:

100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 250 260 270 280 290

Figure 1:

Maximum tripping time depending on the overload for AC motors

Permissible heat sink temperature is exceeded, leading to the error message

"OH (Error overheat powermodules)".

Exceeding the tripping time leads to the error message "ERROR overload",
