Technical Specifications
590+ Series DC Digital Converter
AC Line Choke (Frames 1, 2, 3, 4 & 5)
To correctly isolate the 590+ drive from the ac power system, and to protect other equipment
from transients on the power system, always use the recommended external ac line choke (or
alternatively a transformer may achieve the necessary isolation).
Note that the Frame 5 requires two ac line chokes
(one in front of each of the paralleled
converters). This provides isolating impedance between the drive and its ac power source. It
also provides the necessary impedance between the paralleled converters, forcing them to
share the total motor current evenly. The Frame 5 drive must still use two ac line chokes when
a transformer is used for isolation, however, the chokes can be of a much lower inductance,
typically 3-5 μH.
Drives below 100A Armature Current rating cannot achieve confromance with EN61800-3
Table 11 using only a 50
P
H line choke. Capacitors must be fitted between phase and earth to
achieve conformance.
