: Ensure the panel cooling is functioning and that the ambient temperature is within limits. For Motoman FS100 Robot Controllers
Power down the main system and wait for the charge LEDs to extinguish fully.
A key takeaway is to always address the mechanical components first, as a mechanical problem cannot be fixed by any software adjustment. Implement a scheduled inspection program that includes checking motor current waveforms for irregularities, verifying that all cooling fans are operational, and regularly testing the movement of mechanical axes for smoothness. For persistent or ambiguous issues, Yaskawa's technical support remains the definitive resource for specialized guidance. yaskawa error code a910 exclusive
: Schedule quarterly cleanings of all control cabinet ventilation filters to ensure continuous airflow around the drive heat sinks.
To minimize occurrences of the warning in automated facilities, implement the following maintenance steps: A.910 fault in Yaskawa Sigma 7 servo drive - Click2Electro : Ensure the panel cooling is functioning and
: The temperature inside the SERVOPACK panel is too high (exceeding 55°C). Remedies :
The warning is typically triggered when the drive detects the motor is working harder than its rated capacity. Common reasons include: To minimize occurrences of the warning in automated
Measure continuity across motor power cable lines (U to ground, V to ground, W to ground) using a high-quality insulation multimeter to confirm there are no active micro-shorts.
The overload warning level is defined by parameter Pn52B . If this is set too low for your specific application, you may get "nuisance" alarms.
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
