Panasonic MINAS A5 Servo Drive Error Err11.0

Panasonic PLC & VFD Critical Power

Model: MINAS A5 | Code: Err11.0

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

Symptoms

The control power supply voltage has dropped below the minimum rated voltage. The servo drive cannot maintain normal operation and triggers a protection alarm.

Possible Causes

  • Control power supply voltage dropped below the rated minimum (typically 200V AC for 200V class or 400V AC for 400V class)
  • Power supply wiring has loose connections or damaged cables
  • Power supply capacity is insufficient for the drive load

Troubleshooting Steps

  1. Step 1: Measure the control power supply voltage at the drive terminals using a multimeter
    Voltage should be within the rated range (200V AC +/-10% for 200V class)
  2. Step 2: Check all power supply wiring connections for looseness or corrosion
    All connections are tight and free of corrosion
  3. Step 3: If voltage is low, check the upstream power supply and transformer capacity
    Power supply can deliver adequate voltage under load
  4. Step 4: If the problem persists, replace the drive's internal power supply board
    New power supply board maintains stable voltage

How to Reset

To reset: 1) Resolve the undervoltage condition. 2) Cycle the control power OFF then ON. 3) Re-enable the servo motor. If the alarm persists, contact technical support.
