Yaskawa Error Code A910 Link May 2026

Yaskawa drives utilize a mathematical model to simulate the heating of the motor.

Note on Multi-Motor Applications: If one drive operates multiple motors, the Electronic Thermal function in the drive cannot accurately protect the motors. In this case, L3-01 should be disabled, and external thermal overloads must be installed on each motor. If L3-01 is enabled in a multi-motor setup, A910 may falsely trigger.


In less than 5% of cases, the drive’s main control board is defective. The socket for the option card may have cracked solder joints or a dead communication controller.

For 90% of A910 applications involving hoists or high-inertia fans, the "Speed Search" function is the fix.

Yaskawa error code A.910 indicates an Overload Warning, acting as a precursor to critical alarms by flagging when a motor operates above its rated torque for an extended period. Troubleshooting steps include checking for excessive mechanical load, verifying wiring/encoder connections, adjusting parameter Pn52B, and managing high environmental temperatures. For comprehensive troubleshooting guides, visit Click2Electro.

The Yaskawa error code A.910 refers to an Overload Warning. This warning is a proactive alert that triggers before a full overload alarm (like A.710 or A.720) occurs, giving you a chance to intervene before the drive shuts down entirely.

To "develop a feature" or solution around this specific link in your system, you should focus on proactive load management and predictive maintenance. Key Technical Details of A.910

Nature of Error: It is a warning, not a hard fault. The drive will continue to run the motor, but the ALM indicator LED will likely flash.

Trigger: The motor is operating for an extended period under a torque that exceeds its rated capacity.

Settable Parameter: You can adjust the threshold for when this warning triggers using parameter Pn52B. Recommended Features to Develop

If you are building a monitoring or control interface, consider implementing the following features: Predictive Shutdown Routine:

Since A.910 is a precursor to a hard stop, develop a routine that detects the A.910 status and automatically scales back the production speed or "reference speed" to reduce torque demand. This keeps the machine running at a lower capacity rather than letting it trip and halt the entire line. Dynamic Parameter Tuning (Pn52B):

Create a "Safety Margin" configuration tool. By adjusting Pn52B, you can set how early you want the warning to trigger. For critical processes, you might want this to trigger at 80% of the overload limit to give operators more reaction time. Mechanical Health Dashboard:

Continuous A.910 warnings often indicate mechanical friction or binding. Develop a feature that logs the frequency of A.910 occurrences over time. A rising trend can serve as a "Maintenance Required" flag for lubricating bearings or checking for mechanical obstructions. Load/Capacity Auditor:

If the system frequently hits A.910 during normal operation, your software could suggest a motor capacity audit. You can calculate if the current load/operating conditions are within the motor's rated duty cycle. Troubleshooting Steps for Developers

If you are seeing this error during development or commissioning, check the following:

Wiring: Verify the servomotor and encoder are correctly wired.

Load Conditions: Reduce the acceleration/deceleration rates if possible.

Mechanical Integrity: Check for any physical problems in the movement path. yaskawa error code a910 link

Hardware Sizing: If the error persists under normal intended use, the motor capacity may be too low for the application. 5.3 Drive Alarms, Faults, and Errors - Amazon S3

The Yaskawa error code Overload Warning , indicating that the servomotor is operating under a continuous torque that exceeds its rated capacity. While a "warning" does not always stop the drive immediately, it serves as a critical alert that the motor or drive is nearing its thermal limit and could soon trigger a hard fault (A.710 or A.720). Yaskawa America Common Causes Excessive Load

: The motor is physically struggling to move the attached weight or is operating against mechanical resistance. Rapid Cycle Times

: Frequent acceleration and deceleration without enough "rest" time for the motor to cool down. Mechanical Binding

: Misaligned rails, lack of lubrication, or debris in the machine causing friction. Incorrect Sizing

: The motor capacity is too small for the actual application requirements. Faulty Wiring/Encoder

: Loose connections in the motor main circuit or encoder issues can cause improper torque control. MachMotion Troubleshooting & Fixes Check Mechanical Systems

Disconnect the motor from the load and check if the machine moves freely by hand.

Inspect for any binding, debris, or mechanical wear that increases friction. Verify Torque Levels Monitor the Torque Reference (Un002) using the drive's Digital Operator

. If the value stays consistently high (near 100% or above), the load is too heavy. Adjust Operation Cycle Decrease the speed or acceleration/deceleration rates.

Increase the dwell (stop) time between moves to allow the motor to dissipate heat. Confirm Wiring

Ensure the motor cables (U, V, W phases) are properly seated and not damaged.

Check for short circuits or ground faults in the main circuit cables. Evaluate Motor/Drive Capacity

Check that the servomotor and SERVOPACK capacities match correctly; the ratio should typically be between 1/4 and 4.

If the application requirements have changed, you may need a higher-capacity motor. MachMotion How to Reset Manual Reset

: Remove the cause of the overload, then execute an alarm reset via the digital operator or a software command. Cycle Power : If the warning persists, turn the control power supply

again after waiting at least five minutes for the capacitors to discharge. MachMotion

While "A910" is commonly mistaken for a Yaskawa code, it is actually a frequent alarm on Siemens SINAMICS and Micromaster drives. On these systems, indicates that the Vdc-max controller has been deactivated because the DC-link voltage has exceeded its limits. Troubleshooting the A910 Alarm

The drive issues this warning when it can no longer keep the DC-link voltage within a safe range, often causing the motor to go into regenerative mode. Check Input Voltage

: Ensure the main supply voltage (parameter P0210) is within the drive's rated range and not permanently too high. Active Loads

: Verify if the motor is being driven by an active load, which pushes the system into regenerative mode. High Inertia

: Check for high load inertias during deceleration. If the ramp-down time is too short, the DC-link voltage will spike. Parameter Settings : Ensure parameter

(Vdc controller configuration) is set correctly for your application. Related Yaskawa Fault Codes

In the Yaskawa ecosystem—specifically for Sigma series servo drives—the error code A.910 is an Overload Warning.

It serves as a preemptive alert that the motor is approaching a critical overload state (Alarms A.710 or A.720). If you ignore it and keep running, the drive will eventually trip a full fault to protect the hardware. Common Causes

Mechanical Overload: The physical load on the motor is too heavy or has become stuck due to mechanical issues.

Wiring Faults: Incorrect or loose wiring at the motor or encoder can trigger this warning.

Capacity Mismatch: The motor may be undersized for the required torque/operating conditions.

High Ambient Temperature: If the temperature inside the control panel exceeds 55°C, it can lead to heat-induced overload warnings. Note on Multi-Motor Applications: If one drive operates

Incorrect Parameter Settings: The "Overload Warning Level" (Pn52B) might be set too low for your specific application. How to Fix It

Check Mechanics: Ensure there are no jams, binding, or excessive friction in your machine.

Verify Wiring: Inspect the motor and encoder cables for any damage or poor connections.

Adjust Parameters: If the load is naturally high but within safety limits, you can adjust the warning threshold using parameter Pn52B.

Cooling: Ensure the control panel has proper ventilation and that the drive's heat sink is clean.

Isolate the Issue: Disconnect the motor from the load and run it alone. If the warning persists, the issue is likely within the drive (SERVOPACK) or the motor itself.
