Yaskawa Error Code A910 Link

If you need to discuss the specific application or get a quote on replacement parts, If you want, I can help you:

The Yaskawa error code indicates an Overload Warning . This is a cautionary status that precedes more critical overload alarms like A.710 (Instantaneous Overload) or A.720 (Continuous Overload). If the underlying cause is not addressed, the drive will eventually trip a full alarm to prevent the servomotor from overheating. Common Causes

Internal component degradation in the driven mechanism adds friction, requiring the motor to draw extra current just to complete standard moves.

When troubleshooting an active A.910 warning link, engineers generally categorize the root issues into mechanical, electrical, and programming categories. 1. Mechanical Binding and Excessive External Load yaskawa error code a910 link

. If the value stays consistently high (near 100% or above), the load is too heavy. Adjust Operation Cycle Decrease the speed or acceleration/deceleration rates.

The table below provides a systematic fault-isolation approach: If you need to discuss the specific application

Check for jammed components, tight bearings, or improper lubrication. If the motor works fine when disconnected, the issue is mechanical.

If the motor is standing still but the drive trips instantly on A910, you likely have a noise issue. Common Causes Internal component degradation in the driven

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.

Improper gain settings or inertia ratio settings in the drive. 4. Servo Drive or Motor Failure Internal failure within the Sigma-7 Servopack. Motor encoder failure. Troubleshooting Step-by-Step

Decouple the servomotor from the load. Manually turn the machine shaft to verify that the axis moves smoothly across its full travel length. Inspect for debris or mechanical misalignment. 2. Undersized Servomotor or Aggressive Motion Profiles
