Derating in case of a phase loss
In case of a phase loss the drive will function according to the settings of parameter
31.21 Supply phase loss. If No action is selected, the output current is limited to 50
% when phase loss is detected. No fault or warning is given.
Fuses
The tables list the fuses for protection against short-circuits in the input power
cable or drive. The operating time depends on the supply network impedance, and
the cross-sectional area and length of the supply cable.
Do not use fuses that have a higher current rating than specified in the table. You
can use fuses from other manufacturers, if they meet the ratings, and if the melting
curve of the fuse does not exceed the melting curve of the fuse mentioned in the
table.
￭
IEC fuses
Either fuse type can be used if it operates rapidly enough.
gG fuses (IEC)
Make sure that the operating time of the fuse is less than 0.5 seconds. Obey the
local regulations.
