Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
The controller detected an instant power failure due to voltage or power issues. The manual's first action is: “Check if the primary power supply voltage is dropping.”
The controller detected an instant power failure affecting torque and servo voltage. The manual's first action is: “Check if the primary power supply voltage is dropping.”
The servo control board has failed. The manual's first action is: “(1)Turn the power OFF then back ON. (2)If the alarm occurs again, replace controller. Save the CMOS.BIN before replace controller to be safe.”
