The Yaskawa CACP-JU15A3BB is a Sigma SD series power regeneration converter, designed to enhance energy efficiency in spindle motor drive systems. Here's a refined summary of its key features:

• Function: Acts as a power regeneration converter, recovering energy during motor deceleration and feeding it back into the power supply.
• Input Voltage: 200 VAC, 3-phase.
• Application: Typically paired with CACR-JU series SERVOPACKs and UAKAJ-series spindle motors for high-performance spindle control.
• Design: Modular, panel-mountable unit suitable for industrial automation environments.
• Stock Status: Often listed as non-stock or limited stock, depending on the configuration.
• CAD Resources: A STEP file model is available for system design and CAD integration.
