If you have a specific Yaskawa model (e.g., GA800, A1000, V1000), reply with the model number and the load type (fan, pump, conveyor, crane) for a tailored parameter list.
Disconnect the servomotor output shaft from the mechanical system.
To help narrow down this issue on your factory floor, tell me:
: Faulty or loose connections in the motor or encoder cables can cause irregular current spikes. yaskawa error code a910 exclusive
The overload warning level for the A.910 code is adjustable. By default, the system is configured to sound the warning at 20% of the time required to trigger an overload alarm. However, if this parameter () has been set too low for your specific application, it can lead to nuisance warnings that may cause unnecessary downtime. In rare cases, the warning can indicate a genuine failure within the SERVOPACK unit itself, which would require replacement.
In many factory-default configurations, the parameter is set to a conservative threshold (such as 20% of the maximum thermal capacity). Under highly dynamic duty cycles with frequent acceleration and deceleration, the system will trigger the warning prematurely despite being well within safe operating limits.
Ensure the ambient panel temperatures remain strictly below . If you have a specific Yaskawa model (e
: The starting torque exceeds the motor's maximum capacity, or there is high friction/interference in the mechanical system.
If you are using a network communication option card (such as EtherNet/IP, Modbus TCP, or PROFINET) or an external digital operator keypad, a momentary break in data transmission can drop a critical heartbeat signal, prompting the drive to register an A910 warning. 4. Firmware Incompatibility or Corruption
Preventing A910 warnings is more efficient than troubleshooting them reactively. A proactive maintenance strategy is key. The overload warning level for the A
In the context of Yaskawa servo drives (such as the Sigma-7, Sigma-5, and Sigma-3 series), is a warning indicating an Overload condition.
Loose or corroded contacts in the main U/V/W motor power cable force the drive to draw imbalanced currents.
Dust, moisture, and conductive particles can create microscopic short circuits on the control board, leading to processing errors. Clean the drive environment regularly.
: The temperature inside the SERVOPACK panel is too high (exceeding 55°C). Remedies :
