Selects reaction of inverter to an internal over-temperature.
Following physical values influence the inverter overload protection (see diagram):
-
heat sink temperature
- junction temperature (IGBT temperature)
- inverter I²t

Possible Settings:
0 Reduce output frequency
1 Trip (F0004)
2 Reduce pulse frequency and output frequency
3 Reduce pulse frequency then trip (F0004)
Notice:
P0290 = 0:
Reduction of output frequency is only effective if the load is also reduced. This is for example valid for
variable torque applications with a quadratic torque characteristic as pumps or fans.
A trip will always result, if the action taken does not sufficiently reduce internal temperature.
The pulse frequency P1800 is reduced only if higher than 2 kHz. The actual pulse frequency is displayed in
parameter r1801.
P0291[3] Inverter protection Min: 0

Bit 02 shows if phase loss dedection (input phase) of 3 phase inverters is enabled after factory reset.
Default setting of phase loss is disabled for FSA - FSC. FSD and greater it is enabled.
Bitfields:
