Yaskawa SCRA-SDA11H01A-YRC1000 – Safety Board Inverter Module | YRC1000 Series Platform
Engineering Background
The SCRA-SDA11H01A is a dedicated safety board inverter module engineered by Yaskawa Electric Corporation for integration within the YRC1000 robot controller platform. Yaskawa’s YRC1000 series represents the current-generation compact controller architecture designed for medium and large industrial robots, including the MOTOMAN SDA, MH, and MA series. This module serves as the core inverter and safety interlock board, managing servo drive power distribution and functional safety (FS) compliance within the controller cabinet.
Product Positioning
Targeted at maintenance engineers, system integrators, and OEM automation builders who require a verified OEM replacement or spare for YRC1000-based robot cells. The SCRA-SDA11H01A-YRC1000 is a direct factory-specification component — not an aftermarket substitute — ensuring full compatibility with Yaskawa’s proprietary servo and safety architecture.

System Architecture & Signal Flow
Within the YRC1000 controller, the SCRA-SDA11H01A sits between the main CPU board and the servo amplifier section. It performs three primary functions:
- Inverter Control: Converts DC bus power to the PWM signals driving each servo axis amplifier stage.
- Safety Monitoring: Continuously monitors STO (Safe Torque Off), SS1, and SS2 safety input states, cutting drive enable signals within the IEC 62061 response time window.
- Fault Isolation: Provides hardware-level fault isolation between the safety circuit and the main motion controller, preventing cascading failures across axes.
Sourcing & Quality Verification
- All units sourced through verified Yaskawa authorized distribution channels or directly from Yaskawa-certified MRO suppliers
- Pre-shipment inspection: visual, connector integrity, and label/serial verification
- Anti-static packaging with humidity indicator card for long-term storage integrity
- Certificate of conformance available upon request for regulated industries
- Counterfeit-prevention: each unit cross-referenced against Yaskawa factory serial database where applicable

Technical FAQ
- Q: Is SCRA-SDA11H01A compatible with YRC1000 micro or small robot variants?
- A: No. This part number is specifically for medium/large robot configurations. Small robot and YRC1000 micro variants use a different SCRA board. Always verify against your controller’s internal label.
- Q: Does this module require Yaskawa service tool programming after installation?
- A: For a like-for-like replacement (same robot model, same controller generation), no parameter changes are typically required. However, Yaskawa recommends running a servo tuning check post-installation. Consult your YRC1000 maintenance manual (HW1483602) for the full procedure.
- Q: What is the typical failure mode that necessitates replacement?
- A: Common failure indicators include alarm codes 0400–0410 (servo drive fault), safety circuit open alarms, or intermittent E-stop faults not attributable to external wiring. A failed SCRA board may also manifest as a single-axis or all-axis servo-off condition at power-up.
- Q: Can Konmask provide installation support?
- A: Yes. Our technical team can provide remote guidance referencing Yaskawa’s official maintenance documentation. Contact support@konmask.com with your controller serial number and alarm history.
