Derating of the output current due to temperature and PWM frequency

INFORMATION

When using a CFX.. gateway, the temperature for calculating the derating must be assumed to be 5 K higher than expected in the control cabinet.

Example:

Expected control cabinet temperature: 45 °C
Temperature for calculating the derating: 45 °C + 5 K = 50 °C

INFORMATION

Interpolate linearly for voltages between 400 V and 500 V.

The following tables show the values for the derating of the output current due to the temperature and PWM frequency:
