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

 

Quick tip:

Check incoming voltage and correct if excessive
