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.
