Output frequency derating

Output frequency derating applies for ratings up to ACH580-01-106A-4 (R5). Inverter
output current is limited by the following factor k below 5 Hz absolute inverter output
frequency f_abs.
k = 2/3 + 1/3 · (f_abs / 5 Hz)

Fuses (IEC)

gG as well as uR or aR fuses for protection against short-circuit in the input power cable
or drive are listed below. Either fuse type can be used for frames R1...R9 if it operates
rapidly enough. The operating time depends on the supply network impedance and the
cross-sectional area and length of the supply cable.
Note 1: See also Implementing short-circuit and thermal overload protection (page
Note 2: Fuses with higher current rating than the recommended ones must not be used.
Note 3: Fuses from other manufacturers can be used if they meet the ratings and the
melting curve of the fuse does not exceed the melting curve of the fuse mentioned in
the table.

gG fuses

Check on the fuse time-current curve to ensure the operating time of the fuse is below
0.5 seconds. Obey the local regulations.
