3.1
Overload function
(from inverter firmware 2.2.0.43)
The permissible overload time is considerably depending on the cooling conditions. The over-
load protection of the inverter is triggered by the following reasons:
•
permissible heat sink temperature is exceeded => OH („Error! Overtemperature“)
• exceeding the disconnecting time in accordance with the characteristic above => OL („Er-
ror! Overload“)

Overload function in the lower speed range (OL2)
in the lower speed range the permissible output current is depending on the output frequency.
Depending on the setting of parameter is14 the error E.OL2 is triggerd or the output current
is limited on exceeding the output current.
