: Intermittent signal drops force the SERVOPACK to compensate with excessive current loops. 3. Aggressive Operating Profiles
If A910 appears intermittently or frequently, the following actions are recommended:
Yaskawa error code A.910 Overload Warning that appears on Sigma series servo drives
is one of the more cryptic yet critical alarms in the Yaskawa drive ecosystem. If you are seeing A910 flash across your HMI (Digital Operator), your drive is not dead—but it is signaling a fundamental breakdown in communication between its internal control board and the optional communication card. yaskawa error code a910 link
Ensure the motor cables (U, V, W phases) are properly seated and not damaged.
If you have recently tuned the system or initialized the SERVOPACK, the gain configurations might be unstable. Excessively high or Integral (Ki) gains can cause the motor to micro-oscillate or hunt at its target position. This continuous micro-correction pulls high current even when the motor appears static. What are the common fault codes of Yaskawa servo drives?
The drive’s serial port may be damaged, requiring drive repair/replacement. : Intermittent signal drops force the SERVOPACK to
Failing to address the A.910 warning will lead directly to the drive shutting down on an This is a critical fault condition that requires a manual reset.
: Check for any physical problems in the movement path.

The that indicates your servo system is operating close to its thermal or torque capacity limits. Unlike a hard fault that instantly shuts down your machinery, the A.910 code acts as a pre-alarm warning displayed on your SERVOPACK before triggering critical fault codes like A.710 or A.720. Ignoring this warning inevitably leads to an unexpected production shutdown when the drive enters a complete fault state.
Seventeen minutes. Not a coincidence. Lin shuffled through the plant’s maintenance calendar and found the culprit: at 2:30 a.m., the HVAC system ran a self-calibration that pinged the building network, flooding the switch with traffic. The timing matched the switch hiccups. The A910 was not a dead wire; it was being drowned out by noise.
The is an overload warning issued by Yaskawa SERVOPACKs to indicate that the servo motor is operating under a continuous torque that exceeds its rated capacity . Unlike hard faults that immediately shut down system operations, this minor code functions as an early warning mechanism. It alerts operators that if the current operating conditions persist, the drive will inevitably upgrade the warning to a critical, machine-stopping A.710 or A.720 overload alarm to protect internal circuits from overheating. Technical Specifications: What is Error Code A.910?
If the system frequently hits A.910 during normal operation, your software could suggest a motor capacity audit. You can calculate if the current load/operating conditions are within the motor's rated duty cycle. Troubleshooting Steps for Developers
