Industrial Robot Motion Control Solution — Yaskawa SRDA-EAXA21A | DX200 Series
Where This Product Is Used
The Yaskawa SRDA-EAXA21A axis control board is the core servo coordination module inside the DX200 robot controller, deployed across high-demand industrial environments worldwide:
- Automotive Assembly Lines — Spot welding, arc welding, and body-in-white handling with Motoman MA, VA, and EA series robots
- Electronics Manufacturing — PCB handling, precision pick-and-place, and component insertion requiring sub-millimeter repeatability
- Metal Fabrication & Cutting — Plasma and laser cutting paths coordinated across 6+ axes via DX200 multi-robot control
- Palletizing & Logistics — High-cycle palletizing with GP-series robots in food, beverage, and consumer goods facilities
- Painting & Coating — Continuous-path spray applications requiring smooth, jerk-free axis interpolation
- Semiconductor Fab & Cleanroom — Wafer handling and inspection with vibration-sensitive motion profiles
Whenever a DX200 controller loses axis synchronization, triggers SRDA alarm codes, or exhibits erratic servo behavior, the SRDA-EAXA21A is the primary board to inspect and replace.

Application-Specific FAQ
Q: Will SRDA-EAXA21A work with my DX100 controller?
A: No. The EAXA21A is designed exclusively for the DX200 platform. DX100 uses a different backplane architecture (SRDA-EAXA01A). Confirm your controller model before ordering.
Q: Do I need to re-teach robot positions after replacing this board?
A: In most cases, no — robot job files and calibration data are stored on the CPU board (SRDA-COA01A), not the axis board. However, always perform a mastering check after any control board replacement per Yaskawa maintenance procedures.
Q: What alarm codes indicate SRDA-EAXA21A failure?
A: Common alarms include 4100–4199 series (axis control errors), 4300 (EAXA communication fault), and servo alarm 8.1xx. Consult your DX200 alarm code manual for exact fault isolation.
Q: Can you supply a matched SRDA-EAXA21A + SRDA-COA01A pair?
A: Yes. Contact us with your controller serial number and we will source a firmware-matched pair to minimize compatibility risk.
Q: Is this board repairable if damaged?
A: Board-level repair is possible for certain fault types (capacitor failure, blown fuses). Contact us to discuss repair vs. replace economics for your situation.
