Yaskawa Error Code A910 Exclusive [2021] Jun 2026

When working with Yaskawa Sigma-7 or Sigma-5 servo drives, encountering an error code can stop production, but understanding that code is the first step toward a quick resolution. The , often defined simply as an "Exclusive" or "Exclusive Selection" error, is a common issue related to configuration, particularly when attempting to use multiple functions or commands simultaneously that cannot operate together.

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.

The most common cause is the misuse of parameter settings in the Pnxxx group.

Disconnect the motor from the load where possible and rotate the driven mechanism manually. For a ball screw actuator, rotate the screw 2–3 turns in each direction while feeling for irregular resistance or grinding.

In the realm of industrial automation, Yaskawa drives (particularly the Sigma-5, Sigma-7, and GA series) are renowned for their reliability. However, encountering an error code can be a frustrating experience for operators and maintenance technicians alike.

Do not swap the drive. Swap the digital operator with a brand new or known working unit from another machine of the exact same model . When working with Yaskawa Sigma-7 or Sigma-5 servo

Disclaimer: When working with servo drives, ensure all safety protocols are followed. Unexpected movement can occur during troubleshooting. If you can tell me: Which (Sigma-5 or Sigma-7)?

A: Yes. A faulty encoder or its wiring can cause a "faulty contact in the motor or encoder wiring" error, which is a listed cause of A.910. If the encoder sends incorrect position or speed feedback, the drive may push more current to the motor than necessary, creating an overload state.

Use Yaskawa's software to look at the diagnostic data. The software will often provide deeper insights into which specific parameters are creating the conflict. Go to Monitor -> Alarm -> Alarm Details . 2. Check for Conflicting Parameters

If you have searched for you are likely not looking for basic troubleshooting. You need the deep, technical breakdown that service manuals gloss over. This article provides that exclusive, in-depth analysis. We will cover what A910 really means, why standard fixes fail, and the proprietary nuances Yaskawa engineers expect you to know.

On a Yaskawa Sigma-7 servo drive, the specifically indicates an Overload Warning . This code is exclusive in the sense that it acts as a preemptive alert, appearing before the drive triggers a more severe, machine-stopping alarm like A.710 or A.720. What is Happening?

While many error codes point to physical hardware failures—such as overcurrent or overheating—Error A910 is distinct because it is an . It signifies an "Exclusive" state where the drive cannot execute the requested command because higher-priority conditions are active.
