For selecting the components in the mains connection, observe
the pieces of information contained in the following chapters:
●
chapter 15.1 "Determining the Appropriate Drive Controller"
●
chapter 15.3.2 "Determining the Mains Filter" on page 264
●
chapter 15.3.1 "Determining the Mains Choke" on page
The connection lines to the drive controllers should preferably
have the same impedances in order to achieve balanced load dis‐
tribution at the power inputs of the drive controllers. From the
common node of the lines, you therefore have to make sure that
●
the lengths of the supply lines and
●
the cross sections of the supply lines are the same.
At the common DC bus there is less than the sum of the device-
specific performance data available. This particularly applies to
the continuous DC bus power P
DC cont
and the continuous regen‐
erative power P
BD
. The sum is generated with reduced perform‐
ance data. The reduction takes place with the corresponding bal‐
ancing factors for parallel operation.
For these data, see Project Planning Manual "Rexroth
IndraDrive Supply Units and Power Sections" → Chapter of the re‐
spective device → "Technical Data" → "Basic Data" → table "Data
of Power Section - DC Bus".
