Derating of the electrical data
The frequency converters FCS01 are dimensioned for certain operating
statuses. Other deviating operating status are possible with derating of
the electrical data. Derating of the output current is executed in
dependence on pulse frequency, output frequency and mains voltage.
Reduction of the output current is effected in case of
• pulse frequency fs > 6 kHz (400V device); 8 kHz (230V device)
• output frequency < 2Hz and DC voltages
• system voltage > 400 V
Refer to the paragraphs below for the resulting electrical data.
Derating of the output current depending on the pulse
frequency
This illustration shows the current reduction based on the pulse frequency
for 230V and 400V devices. With 400V devices, reduction starts with a
pulse frequency of 6kHz. With 230V devices, it starts with a pulse
frequency of 8 kHz. In case of higher pulse frequency, the current is
reduced insofar that the power dissipation in the power section remains
more or less constant.

Derating overload capacity depending on overload
duration
Depending on the duration of an overload, the available overload capacity
changes. When the overload capacity limit is reached, the frequency
converter must be operated with lower capacity utilization before it is
overloaded once more.
