Temperature monitoring of the Inverter
Selects reaction of inverter to an internal thermal overload condition.
0: Reduce output frequency and output current
1: No reduction, trip (F0004/ 5/ 6) when thermal limits reached
2: Reduce pulse frequency, output current and output frequency
3: Reduce pulse freq. only and trip (F0006) when overload too high
The following physical values influence the inverter overload protection (see dia-
gram):
Heat sink temperature (r0037[0]); causes A0504 and F0004.
•
IGBT Junction temperature (r0037[1]); causes F0004 or F0006.
•
Delta temperature between heat sink and junction temperature; causes A0504
•
and F0006.
Inverter I t (r0036); causes A0505 and F0005.
