Several factors can contribute to the occurrence of the A910 exclusive error code. Some of the most common causes include:
The A.910 warning indicates that the servomotor is operating near its capacity, or the load on the system is higher than the rated torque for an extended period.
Excessive friction or mechanical jams in the driven equipment.
: Verify all motor and encoder connections are secure and correct. yaskawa error code a910 exclusive
⚠️ : Changing L2-05 to 2 (alarm only) or increasing ride-through times may cause unpredictable motor behavior if voltage drops too low. Use only when power fluctuations are minor and your process can tolerate reduced torque.
For detailed technical specifications, you can refer to the official Yaskawa Sigma-5 Alarm Troubleshooting Guide MachMotion Drive Error List specific parameter settings for your drive model to adjust these warning thresholds?
In one repair case, a customer reported a Yaskawa Servopack (SGDV-120A01AY101AA) was displaying error codes A.710 and A.910 with highly unstable motor behavior. Several factors can contribute to the occurrence of
By default, the A910 warning is triggered when the load reaches of the threshold required to cause an overload alarm. This built-in margin is a sophisticated protection feature, creating a "safety buffer" between normal operation and critical overload.
| Scenario | Repair Cost | Success Rate | Recommended Action | | :--- | :--- | :--- | :--- | | Ripple on +5V > 100mV | $200 (re-cap) | 90% | Send control board to electronics repair shop. | | Operator works on other drive | $75 (new JVOP) | 100% | Replace digital operator. | | Operator fails on multiple drives | $400+ | 10% | Inspect main power ground; replace bonding jumpers. | | FFC cable wiggling causes error | $15 (cable) | 99% | Replace FFC cable (part # EC0A234...). | | Drive is GA800 with old FW | $0 (update) | 95% | Update firmware to v7.11 or later. |
: The torque required by the application is consistently exceeding the motor's rated capacity. High Ambient Temperature : If the environment around the motor or drive exceeds : Verify all motor and encoder connections are
The Yaskawa error code (often displayed as A.910 ) indicates a "Momentary Power Loss" or "Undervoltage during Run" fault on Yaskawa AC drives (e.g., A1000, V1000, J1000, GA500, GA800 series).
