By recognizing the Yaskawa A910 code as a helpful early-warning system rather than a catastrophic failure, you can catch mechanical and programming issues early—saving your hardware from damage and eliminating unexpected downtime.
The most common cause is a load that exceeds the motor's rated torque capacity due to mechanical binding or increased friction in the system. yaskawa error code a910
The A910 code is a warning with the official name Its primary function is to alert the user before a more severe overload alarm, specifically A.710 (High-Load Overload Alarm) or A.720 (Low-Load Overload Alarm), is triggered. By recognizing the Yaskawa A910 code as a
If the air filters on your electrical enclosure are clogged, or if the drive's internal heatsink fins are blanketed in dust, the drive cannot dissipate heat effectively. Even if the fan is spinning, the restricted airflow can trigger a pre-overheat alarm categorized under the A910 umbrella. Step-by-Step Guide to Fix Error Code A910 If the air filters on your electrical enclosure
In the Yaskawa ecosystem, codes starting with "A" generally denote . Unlike a hard "Fault" (which usually trips the drive immediately and cuts power to the motor), an alarm is often a warning that the drive is operating under abnormal conditions or that a non-critical event has occurred.
On Yaskawa SERVOPACKs, is not an outright alarm; it is a warning code indicating an Overload Warning .
Electrolytic capacitors have a finite lifespan—typically 5 to 10 years under normal operating temperatures. As capacitors dry out, their Equivalent Series Resistance (ESR) rises. They can no longer "hold" the DC voltage steady, especially under fluctuating loads. You will see A910 occur intermittently, often during load transients.
