YASKAWA SRDA Series Technical Notes

The YASKAWA SRDA (Servo Drive) series, together with the DEPX and FEPX reducer assemblies, constitutes the core motion-control and power-transmission backbone of the YASKAWA Motoman industrial robot platform. Deployed across petrochemical refineries, nuclear facility material-handling cells, automotive body-in-white welding lines, and heavy-fabrication plants globally, these components are engineered to IEC 61800 servo drive standards and are rated for continuous-duty operation in Class F insulation environments. The SRDA servo amplifier family provides closed-loop torque, velocity, and position control for each robot axis, while the DEPX and FEPX harmonic-drive reducer units deliver the high reduction ratios (typically 1:80 to 1:160) required for precise, backlash-free joint articulation in 6-axis and 7-axis Motoman manipulators. The installed base of SRDA-series hardware spans multiple robot generations—UP, ES, HP, MA, MS, and MH series—making lifecycle parts management a critical operational requirement for maintenance engineers worldwide.

The Evolution of SRDA / DEPX / FEPX Architecture

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.
