Panasonic MINAS A5 Servo Drive Error Err14.0

Panasonic PLC & VFD Critical Current

Model: MINAS A5 | Code: Err14.0

Applicable Systems
MINAS A5 MINAS A6 MINAS A5II FP-X FP7

Symptoms

The servo drive output current has exceeded the overcurrent protection threshold. This indicates a serious fault in the motor or drive power stage.

Possible Causes

  • Motor winding short circuit or ground fault
  • Motor cable is shorted or has insulation breakdown
  • IGBT power module in the drive is damaged
  • Excessive load causing current to exceed rated value

Troubleshooting Steps

  1. Step 1: Disconnect the motor cables and check motor winding resistance and insulation
    Motor windings show balanced resistance and good insulation to ground
  2. Step 2: Inspect motor cables for damage or short circuits
    Cables are intact with no shorts between phases or to ground
  3. Step 3: If motor and cables are OK, the IGBT module may be damaged - replace the drive or repair the power stage
    Drive power stage is functional after replacement
  4. Step 4: Verify the load is not mechanically seized or excessively heavy
    Motor can rotate freely without excessive load

How to Reset

To reset: 1) Resolve the short circuit or overload condition. 2) Cycle power OFF then ON. 3) Re-enable the servo. Do NOT reset without fixing the root cause - IGBT damage may result.
