Figure 185: Current derating at changed operating conditions
For the following operating conditions correction factors are used during the current der-
ating at changed operating conditions:
m
Control cabinet temperature of device (ambient temperature or surface tempera-
ture): Required temperature can be entered in
Z
175.3
–
.
m
Installation altitude: Required installation altitude can be entered in
Z
175.4
–
.
m
Voltage supply (mains voltage/DC link voltage): Required mains voltage or DC link
voltage can be entered in
Z
175.5
–
or
Z
175.6
–
.
m
Current derating dependent of the output frequency
Z
47.49
–
.
This is described in the chapter "Correction factors at changed operating conditions" and
"Electrical data" in the operating manual.
Initialization I

t sub-model
The I

t-sub-model is set or initialized to the following value, if the heatsink temperature
exceeds 45 °C during the operating enable.
Protective function current limit
I
2
t-sub-model:
This model was implemented for components of the device, whose thermal load isn't de-
pendent of the switching frequency. The input value is standardized using the actual val-
ue of the PU-I
