Think of it as the motor's "check engine" light specifically for physical stress. 🛠️ What is happening?
Check if panel fans are working or if the heat sink is obstructed.
Yaskawa AC drives (inverters) are industry standards for precise motor control and reliability. However, like any complex industrial automation component, they utilize a sophisticated diagnostic system to protect both the drive and the connected machinery. One specific code that operators and maintenance technicians encounter is .
: The most common culprit is excessive physical load. Check the motor and connected machinery for physical obstructions, worn parts, or misalignment. Wiring and Contact Faults yaskawa error code a910 exclusive
A910 Exclusive = resource/session ownership prevents access; find and release the owning session (or safely power-cycle) after ensuring the machine is secure.
Have the following ready for Yaskawa support:
If the SERVOPACK capacity is significantly lower than the servomotor it is trying to drive, the system may struggle to maintain the required torque. Think of it as the motor's "check engine"
When A.910 appears, follow this structured diagnostic sequence:
: During normal machine validation, log the baseline temperature of the motors and the nominal operating current via Un002 . Sudden variations in these logs provide early detection of mechanical wear.
Ensure the drive chassis is connected to a low-impedance system ground. Yaskawa AC drives (inverters) are industry standards for
Attempt a controlled release
You need an oscilloscope or a true-RMS multimeter with a bandwidth of at least 100kHz.
Errors in parameters related to torque limits or current levels can cause the drive to report an overload prematurely. Troubleshooting and Solutions
