Chapter 5 Regenerative Bus Supply Configurations With Active Shunt
Typical System Configuration
In this example, standalone AC drives with an external passive shunt, Kinetix 6x00 drives, and Kinetix 7000 drives receive DC-bus power from
the 2198-RP200 regenerative bus supply.
Figure 28 - Regenerative Bus Supply with Standalone AC Drives, Kinetix 6x00 Drives, Kinetix 7000 Drives, and External Passive Shunt
(1) A line reactor can be required. For line reactor selection, see the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002.
(2) Kinetix 5700 regenerative bus supplies require an isolation transformer when connected to corner-grounded or ungrounded facility power.
(3) Kinetix 5700 regenerative bus supplies in mixed common-bus systems require a DC-bus conditioner module in the power supply cluster.
(4) External passive shunt resistor. For minimum ohms with PowerFlex 750-Series drives, see PowerFlex Dynamic Braking Resistor Calculator Application Technique, publication PFLEX-AT001
.
(5) Connect the shunt resistor (braking IGBT) to the largest frame size drive.
