LVD bending machines typically have a variety of error codes that may appear due to issues in the hydraulic, electrical, or software systems. Here’s a list of common error codes and solutions:
### 1. **Error E01: Hydraulic Pressure Failure**
 - **Cause:** Insufficient hydraulic pressure.
 - **Solution:**
 - Check the hydraulic oil level and refill if low.
 - Inspect for any leaks in the hydraulic lines.
 - Ensure all connections are secure, and the hydraulic pump is functioning correctly.
### 2. **Error E02: Motor Overload**
 - **Cause:** Motor overload due to excessive load or obstruction.
 - **Solution:**
 - Verify the load and ensure it’s within the machine’s capacity.
 - Check for obstructions or mechanical resistance in the system.
 - Allow the motor to cool down before restarting.
### 3. **Error E05: Backgauge Malfunction**
 - **Cause:** The backgauge is not responding or is misaligned.
 - **Solution:**
 - Inspect the backgauge alignment and recalibrate if necessary.
 - Check the backgauge motor and connections for issues.
 - Clear any debris or obstacles that may be blocking movement.
### 4. **Error E07: Axis Limit Exceeded**
 - **Cause:** Axis has moved beyond its programmed limit.
 - **Solution:**
 - Verify the programmed parameters and ensure they are within safe limits.
 - Reinitialize or reset the axis to bring it back within the operational range.
 - Check for encoder or sensor malfunctions.
### 5. **Error E09: Safety Circuit Activated**
 - **Cause:** Safety devices like guards or emergency stops have been activated.
 - **Solution:**
 - Inspect all safety devices and reset any that have been triggered.
 - Check for any obstructions around the safety guards.
 - Verify the integrity of the safety circuits.
### 6. **Error E12: Control System Error**
 - **Cause:** Problem with the main control system.
 - **Solution:**
 - Restart the control system.
 - Update the software or reflash if the error persists.
 - Contact LVD support for further diagnostics if necessary.
### 7. **Error E15: Calibration Error**
 - **Cause:** Misalignment or calibration issue with one of the axes.
 - **Solution:**
 - Run the calibration procedure as recommended by LVD.
 - Inspect sensors and encoders on the affected axis.
 - Ensure the machine is set up on a stable, level surface.
### 8. **Error E20: Overtemperature Fault**
 - **Cause:** Excessive temperature detected in the machine components.
 - **Solution:**
 - Check for adequate cooling and ensure fans are working.
 - Inspect ventilation for blockages and clean as needed.
 - Allow the machine to cool down before resuming operation.
### 9. **Error E25: Communication Fault**
 - **Cause:** Communication issue between the control panel and other machine components.
 - **Solution:**
 - Check all cable connections between the controller and components.
 - Restart the machine to reset communication channels.
 - Replace or repair damaged cables if needed.
### 10. **Error E30: Memory/Storage Failure**
 - **Cause:** Issues with the machine’s internal memory or storage.
 - **Solution:**
 - Clear unnecessary files to free up storage.
 - Reinstall software if corruption is suspected.
 - Consult LVD support for assistance with memory-related issues.
Always consult the specific manual or documentation for your LVD bending machine model for precise troubleshooting steps, as error codes can vary by model.
