Manually rotate the machine (with power off) to feel for stiff spots, grinding, or resistance. Adjust Parameters (Carefully): You can delay the A.910 warning by increasing the value in , but this
The A.910 warning is triggered by one of these common system stresses: Mechanical Binding or Jamming: yaskawa error code a910 exclusive
The code acts as a warning that the drive is approaching an overload state (specifically alarms A.710 or A.720). Manually rotate the machine (with power off) to
| Cause | Explanation | |-------|-------------| | | The relay that bypasses the charging resistor is stuck open. | | Blown charging resistor | The resistor that limits inrush current is open-circuited. | | Low input voltage | Severe brownout or missing phase during power-up. | | DC bus short circuit | An IGBT module failure or external short on DC terminals. | | Control board failure | Rare, but the voltage detection circuit can malfunction. | | | Blown charging resistor | The resistor
