Overview

The YASKAWA DF9300131-H2EJAMSC-B2500 is a high-performance regenerative inverter module designed for Yaskawa servo drive systems. It delivers precise AC power to servo motors while incorporating regenerative energy recovery, which captures kinetic energy during braking and feeds it back into the system. This not only improves energy efficiency but also reduces heat load in control cabinets, supporting long-term reliability in demanding industrial automation environments.

The module is ideal for high-speed, high-cycle motion applications, where rapid acceleration, deceleration, and frequent direction changes are common. Its compact and power-dense design allows for optimized cabinet layout without sacrificing performance.

Technical Data

Typical Applications

• High-Speed Robotics: Powers multi-axis industrial robots, handling rapid acceleration/deceleration cycles with energy recovery.

• Automated Storage & Retrieval Systems (AS/RS): Captures kinetic energy from repetitive vertical movements, feeding it back to the DC bus.

• CNC Machine Tools: Supplies precise, dynamic power to spindles and feed axes for high-precision machining.

• Packaging & Converting Equipment: Supports repeated indexing, cutting, or forming actions with efficient energy recapture.

By integrating this module, facilities can achieve enhanced motion performance, reduced energy costs, and lower thermal stress on control cabinet components.

FAQ

Q1: How does the regenerative function reduce heat in the control cabinet?
A1: Traditional braking resistors dissipate kinetic energy as heat. The regenerative module recaptures this energy and returns it to the AC line, reducing cabinet heat and prolonging the life of nearby electronics.

Q2: Is this a complete servo drive system?
A2: No, the DF9300131-H2EJAMSC-B2500 is a power conversion module. It requires a Yaskawa Servo Controller to handle motion logic, PLC communication, and command execution.

Q3: What benefit does this module provide for overhauling or vertical loads?
A3: In vertical or overhauling axes, descending loads push energy back into the drive. The regenerative module efficiently captures this energy, preventing DC bus overvoltage and removing the need for external braking resistors or choppers.
