What causes Haas alarm 1310?

Excessive following error caused by mechanical binding, crash damage, or ballscrew/bearing failure creating high resistance to motion. Servo amplifier overheating due to blocked cooling fans, failed internal fan, or excessive ambient temperature in the electrical cabinet. Loss of encoder feedback signal from damaged encoder cable, loose connections at the motor or servo amp, or failed encoder. Shorted motor winding or motor-to-ground fault causing the amplifier to detect overcurrent condition. Intermittent communication loss between MOCON and servo amplifier due to loose ribbon cables or corroded connectors on the MOCON board.

How do I fix Haas alarm 1310?

1. Step 1: Note which axis is faulted and press RESET to attempt to clear the alarm, then check Diagnostics page for specific servo fault code number 2. Step 2: Verify all encoder cable connections are tight at both motor and servo amplifier, inspect cables for damage or pinch points 3. Step 3: Check servo amplifier cooling fans are operating and cabinet temperature is below 110 degrees F, clean any dust buildup on heatsinks 4. Step 4: Manually rotate the affected axis by hand in MDI mode at low feedrate to detect mechanical binding or abnormal resistance 5. Step 5: Measure motor winding resistance phase-to-phase and phase-to-ground with meter to detect shorted or grounded motor windings 6. Step 6: Swap servo amplifier with known good axis to determine if fault follows the amplifier or stays with the axis, replace failed component

Haas Alarm 1310 - Servo Drive Fault Code

Alarm 1310 indicates a servo drive has detected an internal fault condition and has shut down to protect itself. This alarm is triggered when the servo amplifier reports fault codes to the NGC control, typically due to overheating, overcurrent conditions, or drive hardware failures.

Servo Drive Fault Code

Root Cause Summary

Alarm 1310 indicates a servo drive has detected an internal fault condition and has shut down to protect itself. This alarm is triggered when the servo amplifier reports fault codes to the NGC control, typically due to overheating, overcurrent conditions, or drive hardware failures.

Safety

Axis not operational
Electrical Hazard: Disconnect power to the CNC machine and servo drive before performing any inspection or maintenance. Lockout/Tagout procedures must be followed.
Mechanical Hazard: Be aware of potential axis movement when troubleshooting servo systems. Ensure the axis is properly supported and cannot move unexpectedly.
High Voltage: Servo drives operate with high voltage. Exercise extreme caution when working near energized components.
Discharge Capacitors: Servo drives contain capacitors that can store a dangerous electrical charge even after power is removed. Allow sufficient time for capacitors to discharge before touching any internal components. Refer to the drive's manual for specific discharge instructions.
Do not attempt repairs beyond your skill level. Contact qualified service personnel for complex troubleshooting and repairs.
Axis is not operational; do not attempt to operate or manually move the axis to avoid injury.
Potential electrical hazards; ensure power is disconnected before performing any checks.

Causes and Fixes

1
Check Drive Temperature Status
Navigate to CURRENT COMMANDS > DIAGNOSTICS > SERVO and observe the drive temperature readings for each axis. Normal operating temperature should be below 70°C.
Use the CTRL+ALT+D diagnostic screen to see real-time servo drive temperatures
2
Inspect Cooling System
Power down machine and check all servo drive cooling fans for proper operation. Clean heat sinks with compressed air and verify cabinet ventilation is not blocked.
Always power down and lockout before accessing electrical cabinet
3
Verify Ambient Conditions
Check that shop ambient temperature is within specification (typically 32-104°F) and ensure adequate clearance around electrical cabinet for airflow.
Install additional cooling fans if ambient temperature consistently exceeds 85°F
4
Reset and Monitor
After cooling system verification, press RESET and monitor drive temperatures during light machining operations to confirm thermal issue is resolved.

DIY Feasiblemedium confidence

Call a technician if:

·Drive hardware replacement needed
·DC bus voltage consistently out of range
·Multiple drives faulting simultaneously

Prevention

Maintain proper cabinet cooling and cleanliness
Monitor servo drive temperatures regularly
Perform monthly inspection of electrical connections
Keep machine ways properly lubricated to reduce servo loading

Common Mistakes

Ignoring cooling system maintenance
Not checking motor parameters after drive replacement
Attempting to run with overheated drives
Swapping drives without transferring parameters
