Yaskawa A.910 error code is an "Overload Warning" commonly encountered in Yaskawa Sigma-series servo drives, such as the Sigma-3, Sigma-5, and Sigma-7.

While it doesn't always immediately stop the motor, it serves as a critical pre-emptive alert that the system is approaching a full overload alarm, which will halt production. Understanding the "Exclusive" Nature of A.910 The A.910 code is unique because it is a warning (Gr.2) rather than a hard fault (Gr.1)

. This means it often appears when the drive's internal thermal monitoring predicts an upcoming failure based on current load trends. Common Causes and Remedies Description Recommended Action Wiring Faults

Incorrect or loose contact in the servomotor or encoder wiring. Inspect and secure all motor and encoder connections. High Load Conditions

The starting or operating torque exceeds the motor's rated capacity. Reconsider load weight or increase motor capacity. Mechanical Issues

Excessive friction or mechanical jams in the driven equipment.

Check for physical obstructions or lubrication issues in the machinery. Environmental Heat

In Yaskawa Sigma-series servo drives (including Sigma-3, 5, and 7), the A.910 error code indicates an Overload Warning.

This is a "minor fault" or pre-alarm meant to alert you that the motor is approaching its thermal limit. If left unaddressed, the drive will eventually escalate to a hard fault like A.710 (Instantaneous Overload) or A.720 (Continuous Overload) and shut down. Common Causes

Mechanical Binding: Physical obstruction or excessive friction in the machine's moving parts.

Operating Beyond Capacity: The load or duty cycle exceeds the motor's rated torque.

Incorrect Wiring: Faulty contact or miswired power/encoder cables.

Parameter Settings: The overload warning level (Pn52B) is set too low for the current application.

High Ambient Temp: Excess heat inside the SERVOPACK panel (typically should be below 55°C). Recommended Solutions

Inspect Mechanics: Check for any physical jams or lubrication issues causing extra drag.

Verify Wiring: Ensure the motor and encoder cables are securely connected and not damaged. yaskawa error code a910 exclusive

Check Parameters: Review the Pn52B parameter to ensure the warning threshold is appropriate for your operation.

Cooling: Check if panel fans are working or if the heat sink is obstructed.

Re-evaluate Sizing: If the error persists under normal operation, you may need a motor with higher torque capacity.

The Yaskawa A.910 error code is an Overload Warning on Yaskawa Sigma-series servo drives (specifically Sigma-3, Sigma-5, and Sigma-7). It is a warning, not a hard fault, meaning the drive is detecting that it is operating near its thermal limit and is about to trigger a hard "A.710" or "A.720" overload trip. 🛠️ Common Causes

Mechanical Bind or Jam: Excessive load caused by friction, worn bearings, or physical obstructions in the machine.

Poor Wiring/Contact: Faulty or loose connections in the motor or encoder cables can cause irregular current spikes.

Under-sized Motor: The operating conditions (torque or speed) exceed the rated capacity of the servomotor.

High Ambient Temperature: If the control panel temperature exceeds 55°C (131°F), the drive cannot dissipate heat effectively.

Incorrect Warning Levels: The parameter Pn52B (Overload Warning Level) may be set too low for the intended application. 🔍 Troubleshooting Steps 1 Check Mechanicals

Disconnect the motor from the load and rotate the shaft by hand to check for binding. 2 Verify Wiring

Inspect U, V, and W power leads and the encoder cable for secure seating and damage. 3 Monitor Torque

Use SigmaWin+ to monitor the "Effective Torque Reference." It should ideally stay below 100%. 4 Check Environment

Ensure cabinet fans are working and internal temperatures are below 55°C. 5 Adjust Pn52B

If the load is naturally high but safe, increase the value of parameter Pn52B to delay the warning. 💡 Pro Tip: Is it a CPU Error?

If you are seeing 0910 on a Yaskawa Motoman Robot controller (like the Go to product viewer dialog for this item.

), this is a CPU Error rather than a drive overload. This usually indicates a failure in the CPU unit or communication between boards and may require a hardware replacement or software re-installation. To help narrow this down, could you tell me: What model of Yaskawa hardware are you using (e.g., Sigma-7 drive Go to product viewer dialog for this item. , Motoman robot)?

Does the error happen immediately at power-up or only during movement? Have there been any recent mechanical changes or crashes? FS100 ALARM CODE 0910 CPU ERROR (CPU-201R) Yaskawa A

On a Yaskawa Sigma-7 servo drive, the A.910 error code specifically indicates an Overload Warning. This code is exclusive in the sense that it acts as a preemptive alert, appearing before the drive triggers a more severe, machine-stopping alarm like A.710 or A.720. What is Happening?

The drive has detected that the motor is operating near its thermal or torque limits. If the current operating conditions continue, the drive will eventually shut down to prevent hardware damage. Common Causes

Mechanical Stress: Increased friction or a physical jam in the machinery is forcing the motor to work harder than usual.

Operating Cycle: The motor's duty cycle (how long it runs vs. how long it rests) is exceeding its rated capacity.

Parameter Settings: The "Overload Warning Level" (specifically parameter Pn52B) may be set too low for your specific application.

Wiring/Hardware: Potential faulty contact in the motor or encoder wiring, or a rare failure within the Yaskawa SERVOPACK itself. How to Resolve It

Inspect the Mechanics: Check for physical obstructions or lack of lubrication in the system the motor is driving.

Review the Duty Cycle: If possible, reduce the motor's speed or increase the dwell (rest) time between movements.

Adjust Pn52B: You can modify the overload warning level to be more suitable for your operation, provided it still protects the motor from actual damage.

Verify Capacity: If this warning is frequent in a new setup, the motor may be undersized for the load it is carrying.

Note for Robot Users: If you are using a Yaskawa Motoman robot (like the NX100 or FS100) and see code 0910, this is a different issue entirely—typically a CPU Error related to communication between internal boards.

4. How to Clear the Fault

Once the physical cause is resolved or parameters are corrected:

  1. The A910 warning may persist until the drive's internal thermal model cools down.
  2. If the drive did not trip (stop), the warning light may turn off automatically after current returns to normal.
  3. If the drive tripped, cycle the power or press the RESET button (assuming the fault has cleared).

Summary Checklist:

  1. Check for mechanical jams.
  2. Match E2-01 to Motor Nameplate FLA.
  3. Ensure motor is not overheating physically.

Additional Resources

For more information on Yaskawa error codes, including the A910 exclusive error code, consult the following resources:

By following the guidelines and solutions outlined in this article, you should be able to resolve the Yaskawa error code A910 exclusive and ensure smooth operation of your Yaskawa equipment.

Immediate safe actions

  1. Put the machine in a safe state: stop motion, engage brakes, and follow plant lockout/tagout procedures.
  2. Do not power-cycle equipment on a live machine where motion could unexpectedly resume.
  3. Notify control-room/operations that you’re performing maintenance.

Why is it “Exclusive”?

Unlike general software or parameter-setting errors (e.g., oC, oH, or bUS errors), A910 is exclusive because:

  1. It is hardware-locked – You cannot clear this error by changing parameters or cycling power if the root cause is physical damage.
  2. It is not user-resettable in most cases – Many Yaskawa alarms can be reset via the HOA keypad or a digital input. A910 often persists until the drive is serviced.
  3. It applies only to specific drive series – For example, in the GA800 series, A910 is exclusive to units with an internal pre-charge relay. Smaller drives without that relay will never see this code.

3. Troubleshooting & Solutions

Step A: Verify the Load

  1. Check the physical machinery. Is there a jam, blockage, or mechanical binding?
  2. Monitor the output current on the drive keypad (U1-03). Is it exceeding the motor nameplate rating?
  3. If the current is high, reduce the load or increase the motor/drive capacity.

Step B: Check Parameter Settings

  1. Check E2-01: Compare the value in E2-01 against the Full Load Amps (FLA) on the motor nameplate. They must match exactly.
    • Note: If E2-01 is set too low, the drive thinks the motor is overloaded even when it is running normally.
  2. Check L1-01: Ensure this matches your motor type.
    • 0: Standard Motor (Fan cooled)
    • 1: Inverter Motor (Forced cooling)

Step C: Check Carrier Frequency

1. The "Zombie Capacitor" Issue (Exclusive Insight)

Yaskawa drives built between 2015-2020 have a known, unpublished sensitivity on the +5V rail that powers the digital operator. As electrolytic capacitors on the control board age, the +5V line can develop high-frequency ripple. The digital operator requires a clean DC signal. Ripple above 50mV peak-to-peak will corrupt the handshake, triggering A910. A standard multimeter will show "5V" and pass the fault, but an oscilloscope reveals the truth.

Common Causes of A910

| Cause | Explanation | |-------|-------------| | Failed pre-charge relay | The relay that bypasses the charging resistor is stuck open. | | Blown charging resistor | The resistor that limits inrush current is open-circuited. | | Low input voltage | Severe brownout or missing phase during power-up. | | DC bus short circuit | An IGBT module failure or external short on DC terminals. | | Control board failure | Rare, but the voltage detection circuit can malfunction. |
