5.2.4 DC Bus/Regen Connector
The DC Bus/Regen Connector consists of a pluggable 4-pin screw-terminal block, and
provides connection to the drives DC Bus and to an external Regen resistor.
Note: On the 3A and 6A Drives, the DC Bus/Regen Connections are located on the
upper three pins of the AC Power/Regen Connector, with -RB on top, followed by -DC
and +RB (note that there is no -Ri connection since these Drives do not have internal
Regen resistors)
Note: On the 12A Drive, the DC Bus/Regen Connections are located on the upper four
pins of the AC Power/Regen Connector, with +RBi on top, followed by -RB, -DC, and
+RB.
5.2.4.1 Bus/Regen Connections
Use the following guidelines when making connections to the Bus/Regen Connector:
•
To use the Regen resistor contained within the Drive (12A and 24A Drives only),
cRi to -RB with a jumper
•
To use an external Regen resistor, connect the resistor bRB and -RB
•
To use DC Bus Sharing between the Drive and one or more additional drives:
•
CRB to the connected drive’s +DCBUS
•
Connect -DC to the connected drive’s -DCBUS
ADDITIONAL SHUNT RESISTOR INFORMATION
Refer to section 4.5 on page 60 for instructions on choosing, mounting, and
connecting Shunt Resistors available from Kollmorgen.
