Yaskawa Error Code A910 -
Inspect encoder cable connections for noise-related issues. If the system is in a high-noise environment, ensure the encoder cable is shielded, and that the shield is grounded properly. 3. Review Parameter Settings Pn402cap P sub n 402 (Overload Warning Level): Check if this setting is too low. Pn400cap P sub n 400 Pn401cap P sub n 401
In some cases, the problem isn't the load at all, but a "whisper" that didn't make it through. Incorrect wiring faulty contact
“Cycle power,” she said to Sal.
If the machine's programming has been altered to increase throughput, the motor may not have enough downtime to cool down. High acceleration rates, aggressive deceleration profiles, or a high number of starts and stops per minute will rapidly build up thermal energy. 3. Faulty Wiring or Poor Contact Issues yaskawa error code a910
: Check for mechanical blockages or reconsider the operating conditions. If the load is consistently too high, you may need a motor with a higher capacity.
Was the warning level (Pn52B) set too low for the current job? Environment: Was the control cabinet overheating?
The encoder is failing to provide accurate positional data, leading the servo pack to miscalculate torque requirements. Inspect encoder cable connections for noise-related issues
The drive utilizes an internal mathematical model to track the thermal profile of both the motor and the amplifier. When the calculated thermal load crosses a user-defined percentage of the total capacity (typically monitored via parameter Pn52B ), the digital operator flashes the A.910 code.
The A910 warning is part of a cluster of related errors concerning the motor's load condition. Understanding them can help you see the full picture:
Jammed machinery or linear guides requiring excessive force. Review Parameter Settings Pn402cap P sub n 402
Industrial environments are rarely pristine. Dust, textile lint, airborne grease, oil mist, or metallic shavings can infiltrate the drive housing. Over time, this debris accumulates on the fan blades and around the spindle, physically restricting the fan from spinning or slowing its RPM below the acceptable threshold. Natural Component Wear and Tear
. The machine doesn't stop yet, but the "warning" light is a clear signal that the drive is feeling the pressure. 1. The Unexpected Resistance The most common cause of the A.910 is a mechanical struggle
It serves as a "pre-alarm" to notify you that the motor is approaching its limit and is about to trigger a critical overload alarm, such as (instantaneous maximum load) or (continuous maximum load). LK Automation Limited Key Details & Troubleshooting What it means
