6.2.4 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.
6.2.4.1 Bus/Regen Connections
Use the following guidelines when making connections to the Bus/Regen Connector:
• To use the Regen resistor contained within the Drive, connect +Ri to -RB with a
jumper
• To use an external Regen resistor, connect the resistor between +RB and -RB
• To use DC Bus Sharing between the Drive and one or more additional drives:
• Connect +RB to the connected drive’s +DCBUS
• Connect -DC to the connected drive’s -DCBUS
6.2.4.2 External Regen Resistors
Although an internal regen resistor is contained within each Drive, there may be
applications that require an external regen resistor. Available external regen resistors
are outlined in Table 6-25. For a detailed description of these resistors, including
mounting information, refer to the Kollmorgen "AKD/S700 Accessories Manual" which
can be found at www.kollmorgen.com.
ADDITIONAL SHUNT RESISTOR INFORMATION
Refer to section 4.5 on page 52 for instructions on choosing, mounting, and
connecting Shunt Resistors available from Kollmorgen.
