Yaskawa Error Code A910 Link ((better)) Jun 2026
The operation pattern (acceleration/deceleration) may exceed the motor’s rated capacity.
Disconnection or scale contamination can simulate rapid torque spikes. Pn52B High-Resolution 24-bit Encoder
Examine the electrical enclosure housing the drive. High ambient temperatures degrade the continuous thermal rating of electronics. Ensure the SERVOPACK cooling fan is operating cleanly and that the absolute internal cabinet air temperature stays below 55°C (131°F).

When operating Yaskawa servo drives—particularly in the Sigma-5 and Sigma-7 series—encountering a fault code can halt production instantly. The is a specific warning alarm that indicates a potential overload condition, often referred to in troubleshooting manuals as a precursor to a more critical failure (like A.710 or A.720).
If the load is consistently high, you may need to reconsider the load requirements or upgrade to a motor with a higher capacity. The is a specific warning alarm that indicates
The is an operational warning code indicating a motor overload or torque peak warning typically found in Yaskawa Sigma series (such as Sigma-3, Sigma-5, and Sigma-7) SERVOPACKs. This code serves as a preventative alert, signaling that the system is operating near its thermal or mechanical limitations before a hard fault trips the machine offline.
| Parameter | Description | Role in A910 | | :--- | :--- | :--- | | | Electronic Thermal Selection | Enables/Disables the protection feature that generates A910. | | L3-02 | Motor Rated Current | Critical. Sets the baseline for the overload calculation. Must match the motor nameplate. | | L3-03 | Electronic Thermal Time | Sets how long the motor can sustain an overload before the alarm/trip occurs. | | L3-04 | Overload Warning Level | Sets the percentage of current that specifically triggers the A910 warning (default is usually very close to the trip point). | | U1-03 | Monitor: Output Current | Used for real-time diagnostics to verify if the motor is actually drawing too many amps. | and Sigma-7) SERVOPACKs.
If the drive's communication timeout (Watchdog) is set too low, minor network jitters can trigger the alarm.
A methodical approach is essential for efficient diagnosis. Use the following step-by-step guide:
