  4. SP9003 SSPA:03 DC Link Fuse Is Broken

The PSM becomes ready (00 is indicated), but the DC link voltage is too low in the SPM. The fuse in the DC link section in the SPM is blown (the power device is damaged or the motor is ground-fault). Alternatively, the JX1A/JX1B connection cable is abnormal. Replace the SPM unit. Check the motor insulation status. Replace the interface cable.

 

Quick tip:

Replace SPM unit
