YASKAWA PGB-2K – Servo Drive PCB Control Board | Sigma Series Platform
Engineering Background
The YASKAWA PGB-2K is a dedicated PCB control board engineered for YASKAWA Sigma series AC servo drives. As the core signal-processing and gate-drive interface board within the servo amplifier assembly, the PGB-2K governs PWM command execution, encoder feedback decoding, and fault-protection logic. Its failure is one of the most common root causes of servo drive malfunction in high-cycle industrial environments.
Product Positioning
Konmask.com supplies the PGB-2K as a precision OEM-equivalent replacement targeting maintenance engineers and procurement teams who require a verified, drop-in solution with minimal downtime. This board is sourced through authenticated industrial channels and undergoes functional verification prior to dispatch.

System Architecture & Signal Flow
Within the YASKAWA Sigma series servo amplifier, the PGB-2K board sits at the intersection of the control CPU and the IGBT power stage. Signal flow is as follows:
- Command Input – Receives position/velocity/torque commands from the host controller (MECHATROLINK, analog, or pulse-train interface)
- Encoder Feedback Decoding – Processes incremental or absolute encoder signals for closed-loop position verification
- PWM Generation – Generates gate-drive PWM signals for the IGBT bridge, controlling motor phase currents
- Fault Monitoring – Continuously monitors overcurrent, overvoltage, undervoltage, and thermal thresholds; triggers protective shutdown and fault code output
- Communication Interface – Relays status and alarm data back to the host system via the drive’s communication bus

Technical FAQ
Q: Is the PGB-2K compatible with all YASKAWA Sigma series drives?
A: The PGB-2K is designed for specific Sigma series amplifier models. Please provide your full drive model number (e.g., SGDV-xxxA) to our team for exact compatibility verification before ordering.
Q: What is the difference between a new and refurbished PGB-2K?
A: New units are unused OEM or OEM-equivalent boards. Refurbished units have been professionally reconditioned, tested, and certified to OEM performance specifications. Both carry Konmask’s 90-day warranty.
Q: Can I send my failed board for repair instead of purchasing a replacement?
A: Yes. Konmask offers board-level repair services. Contact [email protected] with photos of the failed board and fault description for a repair assessment.
Q: What fault codes typically indicate PGB-2K failure?
A: Common indicators include A.400 (parameter setting error), A.710 (overload), A.820 (regenerative overload), and drive-level communication faults. However, board failure diagnosis should be confirmed by a qualified servo technician.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Technical documentation is available upon request for verified engineering inquiries. Contact our team with your application details.
