Inspect all connections and ensure the encoder is properly grounded.
The load exceeds the motor's starting or continuous torque capacity, often due to mechanical binding or high inertia. yaskawa error code a910 link
A910 Designation: Overload Warning (Electronic Thermal Alarm) Severity: Warning (The drive remains operational but is at risk of a future trip). System Family: Yaskawa AC Drives (Varispeed G7, A1000, V1000, GA700, etc.) Inspect all connections and ensure the encoder is
If ignored, the warning typically escalates to a full "Overload" alarm (A.710 for high load or A.720 for low load), which will stop motor operation. Common Causes & Troubleshooting System Family: Yaskawa AC Drives (Varispeed G7, A1000,
In simple terms, this error occurs when the Yaskawa VFD (Variable Frequency Drive) attempts to start the motor, but the speed sensor (Encoder or PG) detects that the motor is already moving—or moving backward—faster than the allowable threshold. It can also happen if the drive commands a stop, but the motor drifts due to external forces.
If you are building a monitoring or control interface, consider implementing the following features: :
