Overvoltage of the DC link section of the Power Supply (PS) was detected. (Power Supply (PS) alarm indication: 7) Power Supply (PS) selection error. (The maximum output specification of the Power Supply (PS) is exceeded.)
1 Check the selected Power Supply (PS).
2 Check the input power voltage and change in power during motor deceleration. If the voltage exceeds 253 VAC (for the 200-V system) or 530 VAC (for the 400-V system), improve the power supply impedance.
