Reduce acceleration rates, extend cycle dwell times, or upgrade to a larger motor. Proactive Strategies to Prevent Overload Warnings

This is a "minor fault" or pre-alarm meant to alert you that the motor is approaching its thermal limit. If left unaddressed, the drive will eventually escalate to a hard fault like (Instantaneous Overload) or A.720 (Continuous Overload) and shut down. Common Causes

specifically indicates a Digital Operator Connection Fault or a Communication Mismatch between the main control board (MCU) and the connected digital keypad (typically a JVOP-180, JVOP-181, or similar LED/LCD operator). yaskawa error code a910 exclusive

If the A.910 code disappears while spinning freely, the bottleneck resides completely within your external machine mechanical joints or binding axis. Step 2: Validate Environmental Conditions

is not a death sentence for your drive. However, treating it like a simple loose connection will lead to repeated downtime and unnecessary replacements. The exclusive insights in this guide—from capacitor ripple testing to FFC wiggling and ghost firmware bugs—equip you to diagnose with surgeon-like precision. Reduce acceleration rates, extend cycle dwell times, or

The overload warning level (Pn52B) is set too low for the current application.

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. However, treating it like a simple loose connection

The drive relies on preset thresholds to trigger warnings before a trip occurs.

Disconnect the motor from the load and rotate the shaft by hand to check for binding. Verify Wiring

), this is a rather than a drive overload. This usually indicates a failure in the CPU unit or communication between boards and may require a hardware replacement or software re-installation. To help narrow this down, could you tell me: What model of Yaskawa hardware are you using (e.g., Sigma-7 drive Go to product viewer dialog for this item. , Motoman robot)?

In Yaskawa systems, the error code generally indicates an Overload Warning (pre-alarm) for servo drives or a CPU Error for specific robot controllers. For Yaskawa Sigma-3, Sigma-5, and Sigma-7 Servo Drives
