GENERAL ELEcTRIcAL DATA 3.3 General electrical data 3.3.1 Switching frequency and temperature The drive controller cooling is designed by way that the heat sink overtemperature threshold is not exceeded at rated conditions. A switching frequency higher than the rat- ed switching frequency also produces higher losses and thus a higher heat sink heating. If the heat sink temperature reaches a critical threshold (T ), the switching frequency can be reduced automatically step by step. -
