We got EUPH warning. the motor running in wild mode. how to fix
E.uPh due to the ripple detection of the DC bus. This is typically caused by a missing phase on the input side of the inverter.
Measure your mains voltage L1-L2, L2-L3, L1-L3 and L1-ground, L2-ground, L3-ground to verify that your supply voltage is balanced and withing the rated specifications.
If the applied voltage is good then there is a problem with the input stage or the DC bus and the unit will need to be repaired or replaced.
