12.10 Protection Functions
12.10.1 Converter Protection
Overload pre-warning
When the frequency converter output current is higher than [C0.29] 'Converter
overload pre-warning level' and lasts for longer than [C0.30] 'Converter overload
pre-warning delay', the 'Converter overload pre-warning' signal will be active on
the selected digital output terminal. The signal will be immediately inactive
when the output current is lower than[C0.29].
The actual overload pre-warning level will be reduced by the output current de-
rating by the equation:
[Actual overload pre-warning level] = [C0.29] x [Derating percentage]
Example: When [C0.29] = 50 %, the derating percentage of the output current at
15 kHz is 51 %, as shown in
chapter "Derating and carrier frequency" on page
.
●
When the carrier frequency is 4 kHz, the output current is 100 % of the rated
current, the actual overload pre-warning level is 50 %, which equals to the
[C0.29].
●
When the carrier frequency is 15 kHz, the output current is derated to 51 % of
the rated current, the actual overload pre-warning level is 50 % x 51 %.
