Planning the electrical installation
What this chapter contains
This chapter contains the instructions that you must follow when selecting the motor,
cables, protections, cable routing and way of operation for the drive system. Always
follow local regulations.
Note: If the recommendations given by ABB are not followed, the drive may
experience problems that the warranty does not cover.
Reference: Technical Guide - publ. no.: 3ADW000163
To which products this chapter applies
This chapter applies to the DCS800-S Size D1...D7.
Options for the drive
Line reactors
for armature (DCS800) and field (DCF800) supply.
When thyristor power converters operate, the line voltage is short-circuited during
commutation from one thyristor to the next. This operation causes voltage dips in the
mains PCC (point of common coupling). For the connection of a power converter
system to the mains, one of the following configurations can be applied:
Configuration A
When using the power converter, a minimum of impedance is
required to ensure proper performance of the snubber circuit. A line
reactor can be used to meet this minimum impedance requirement.
The value must therefore not drop below 1% u
k
(relative impedance
voltage). It should not exceed 10% u
k
, due to considerable voltage
drops at converter output.
