Code A910 Exclusive: Yaskawa Error

Inspect the motor power cable connections (Phases U, V, W) and encoder connectors.

While is a standard undervoltage (power loss at stop or standby), A910 is exclusive to Run-time undervoltage .

The parameter determines the precise threshold where the A.910 warning triggers. By default, it is set to alert the operator when the motor reaches 20% to 100% of its thermal load capacity. If an engineer sets this value too low, the drive will flag warnings during standard operating conditions. 5. Excessive Cabinet Temperatures

If A.910 appears without any motion command, suspect a severe electrical problem—most likely a short circuit in the motor cables or a phase-to-phase short inside the motor itself. Power down immediately and check for visible damage. yaskawa error code a910 exclusive

If the A910 code continuously reappears after cycling power, replacing option cards, and isolating noise, the internal control board may have suffered physical degradation. In this scenario, contact an authorized Yaskawa service center or your local distributor for a board-level diagnostic or replacement.

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.

: Increased friction or a physical jam in the machinery is forcing the motor to work harder than usual. Inspect the motor power cable connections (Phases U,

. Unlike critical "faults" that immediately shut down the system, this is an alarm indicating the motor is operating near its capacity limit and is at risk of a full overload trip (A.710 or A.720). Understanding the A.910 Alarm

The is a warning that signals an overload condition in a servo drive. Specifically, this code indicates that the motor or drive is operating near its capacity and is at risk of triggering a full "Overload" alarm—either A.710 (instantaneous maximum load) or A.720 (continuous maximum load). What Does the A.910 Error Mean?

Errors in parameters related to torque limits or current levels can cause the drive to report an overload prematurely. Troubleshooting and Solutions By default, it is set to alert the

: Power cycle the controller. If the error persists, the CPU board may need replacement by a Yaskawa representative . Table 1 - Yaskawa

If your application inherently experiences brief torque spikes (e.g., during acceleration or cutting engagement), you may need to increase this value to avoid nuisance warnings. However, never set it so high that it defeats the protective purpose of the warning.
