✅ Amada RG Press Brake Error Codes and Definitions

If you’re operating an Amada RG Series Press Brake and encounter error messages or issues, this guide lists the most common error codes found across RG models including the RG-25, RG-50, RG-80, RG-100, and RG-125. These errors primarily relate to older NC9, NC9-EX, and NC9-EX II control systems and hydraulic/mechanical components.

🔧 Common Amada RG Error Codes

Error Code	Definition / Action
E01	Emergency Stop Activated – Check all e-stop buttons and reset the system.
E02	Foot Pedal Fault – Foot switch is not engaged or has a loose/disconnected wire.
E03	Ram Not Returning – Inspect hydraulic return settings, limit switches, or obstruction.
E04	Backgauge Servo Fault – Check motor drive, power supply, and alignment.
E05	Low Hydraulic Pressure – Check hydraulic pump performance and pressure gauge.
E06	Ram Position Error – Ram failed to reach programmed position; verify encoder or servo response.
E07	NC Memory Error – Control memory failure, often due to a dead battery or corrupted data.
E08	Ram Overload Detected – Tonnage exceeds set limit; verify part thickness and tonnage setting.
E09	Dual Foot Switch Signal – Both foot pedals pressed at once; inspect switch or misuse.
E10	Backgauge Overtravel – Gauge exceeds safe travel range; adjust settings and check stops.
E11	Servo Amplifier Error – Fault in servo drive; reset or check for overheating/damage.
E12	TDC (Top Dead Center) Not Reached – Faulty limit switch or mechanical obstruction.
E13	BDC (Bottom Dead Center) Not Reached – Ensure stroke is fully completing; check sensors.
E14	Ram Speed Error – Incorrect ram descent or return speed; check hydraulic valve or sensors.
E15	Encoder Signal Lost – Faulty or disconnected ram position encoder.
E16	Clutch Engagement Fault (for mechanical models) – Clutch not engaging properly.
E17	Hydraulic Oil Overheating – Check oil cooler and confirm operating temp range.
E18	Program Not Found – Program not stored or corrupted. Reload or reenter program data.
E19	Tool Calibration Error – Tooling mismatch or height not set correctly.
E20	Limit Switch Fault – A sensor or mechanical limit switch has failed or been triggered.

📌 Tips for Troubleshooting

• Always power off the machine before checking internal wiring or replacing components.
• Clear all error messages by cycling power or performing a system reset.
• Check hydraulic fluid levels and filters regularly to avoid heat-related or pressure issues.
• Backup programs frequently if using NC9/NC9-EX controls—battery failure can erase memory.

📘 Important Notes:

• These codes apply broadly across Amada RG-Series Press Brakes from the 1980s through early 2000s.
• For detailed wiring diagrams or troubleshooting flowcharts, refer to your specific Amada operator’s manual.
• Consider replacing memory backup batteries every 12–24 months to prevent data loss.
