System Description

The QUERCUS servo drive by FAGOR is a compact and stackable
designed PDS. It is connected directly to a TN or TT three-phase mains
with line frequencies of between 50 (1-4 %) Hz and 60 (1+3.3 %) Hz and
line voltages between and 400 (1-10 %) V AC and 480 (1+10 %) V AC.
This system supplies the electric motors with a three-phase voltage of 400
(1- 4.5 %) V AC and a variable frequency with which it will govern its
speed.
Certain mandatory protection elements must be added between the mains
and the QC-PDS system. Others may be optional. These elements are:
