Yaskawa Error Code A910 Link _hot_ Jun 2026
| Symptom | Likely Cause | Recommended Fix | | :--- | :--- | :--- | | | Electrical Noise / Bad Encoder | Check cable shielding; Replace encoder; Check PG card. | | Motor is coasting (spinning) on start | High inertia load / Gravity | Enable Speed Search (b3-02 = 1) or increase b3-01 threshold. | | Error occurs after maintenance | Wiring swapped or Param mismatch | Swap motor leads (U/V/W) OR adjust parameter F1-02 . Verify F1-01 matches new encoder. | | Error occurs during decel only | Regeneration / Load pushing motor | Adjust deceleration time (C1-02) or check braking resistor. |
: Excessive load on the motor due to mechanical friction or a physical obstruction. Operating Conditions
Disconnect the motor from the machine mechanics (if possible) and check for ease of movement. yaskawa error code a910 link
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.
Excessive temperature within the servo panel (exceeding | Symptom | Likely Cause | Recommended Fix
The is fundamentally a communication handshake problem between the drive’s brain and its add-on card. It is rarely a catastrophic failure; more often, it is a loose screw, a dirty contact, or a parameter mismatch.
Based on Yaskawa documentation and field experience, the A910 warning can be triggered by several primary factors: Verify F1-01 matches new encoder
The drive’s serial port may be damaged, requiring drive repair/replacement.
: The mechanical load attached to the motor shaft requires more starting torque than the maximum rated capacity of the motor configuration.
If your machine displays A.910, follow these steps to resolve the issue: 1. Check Wiring Connections (Encoder and Motor)
