Figure 6.42 – DC link removal
Installation of the replacement DC link is performed in the reverse
order of its removal.
The installer must ensure that the flexible DC link leads are
connected to the appropriate terminal and routed so that electrical
clearances are maintained. You must also verify that the nameplate
ratings are the same or appropriate for the drive system. A different
DC link will require different parameter settings.
The DC link maintains a ripple-free current between the line
converter and the machine converter. Thermal protection of the DC
link reactor is provided by two normally closed contacts wired to the
I/O module. These contacts will open at 190°C and cause a
fault/alarm message to be displayed.
