Yaskawa Error Code A910 May 2026

Summary — Yaskawa error code A910

• Poor contact or incorrect wiring between the servomotor and the encoder can trigger false or early warnings.

  in the power or encoder cables can cause erratic readings. The drive misinterprets these signals as a struggle to move, triggering the warning even if the mechanics are perfectly smooth. How the Story Ends (Troubleshooting) yaskawa error code a910

  How to Clear Error Code A910

  1. Automatic Reset: If the power restores and the undervoltage condition lasts less than 100ms (or the time set in L2-02), the drive may resume operation automatically.
  2. Manual Reset:

     Step 5: Load Disconnect Test

     • Remove the motor leads from the drive output (T1, T2, T3).
     • Run the drive at a low reference frequency (e.g., 10 Hz).
     • If A910 disappears, the motor or load is causing excessive current demand, which in turn causes voltage drop. Check motor insulation and load binding.

     She traced the wire back to a junction box near the ceiling, where a bundle of conduit entered. The box was warm. Too warm for 2:00 AM in an unheated part of the mill. Summary — Yaskawa error code A910

     Always start with the simple things—measure your incoming voltage, tighten all connections, and disable momentary power loss ride-thru as a diagnostic step. Do not repeatedly reset the alarm without investigating; each undervoltage event stresses the drive’s front-end components. Poor contact or incorrect wiring between the servomotor

     • Verify E2-01 (Motor Rated Current) matches the nameplate on the motor exactly.
     • Check L3-02 (Stall Prevention Level during Run). If set to the default (usually 150-160%), try increasing it slightly only if the motor and cabling can handle the extra current.
