NOTE!
The DI2 is the only one that cannot be used as PTC input, because it has input circuit dedicated to
frequency input (FI).
Figure 15.3 on page 15-5 shows the PTC connection to the inverter terminals for both situations: via analog input
(a) and via digital input (b) .

15.4 IGBTS OVERTEMPERATURE PROTECTION (F0051 AND A0050)
The power module temperature is monitored and indicated in parameter P0030 in degrees Celsius. This value is
constantly compared to the overtemperature fault and alarm trigger value of the power module F0051 and A0050,
according to
Table 15.2 on page 15-5 where the level for actuation of the alarm A0050 is fixed at 5 ºC (41 °F)
below the level of F0051.

Besides the alarm indication A0050, the overtemperature protection automatically reduces the switching frequency
(P0297) for the value of 2500 Hz. This overtemperature protection characteristic can be deactivated in the control
configuration parameter P0397.
