Cause : Converter cooling faulty (active in operating states of ≤ o13)
The heatsink temperature monitoring function is activated 6s after connection of the electronics supply.

(The current heat sink temperature is indicated at parameter r013 and on connector K050)

Fault value:      r047 Index 002 to 016:

1. Heatsink temperature > permissible heatsink temperature (depending on the MLFB) - i002 Measured heatsink temperature (16384 .. 100°C)

2. Heatsink temperature sensor is defective - i003 Measured ADC value

3. Converter fan is defective.
