Parallel connection of several regenerative power supply modules
[7-183] Parallel connection of several regenerative power supply modules
• When the derating factors are complied with, the operation of several regenerative power sup-
ply modules in the DC-bus connection is permitted.
• The arrangement in the DSD can only be dimensioned with regenerative power supply modules
9400.
• The regenerative power supply modules can be each dimensioned separately in the DSD.
• The selection table in the DSD provides regenerative power supply modules 9400 connected
in parallel (2 × E94... or 3 × E94...).
Single-axis application
For applications with a high regenerative power (e. g. unwinders and hoists) it may also be reason-
able to use a regenerative power supply module for a drive axis.
