When a fault condition occurs, the drive will display the fault code, overridin g the status code. The decimal point is “On” when the dr ive is enabled and the Stop input is not active.
34 Epsilon Eb Digital Ser vo Driv e Installati on Manual Fault Codes A number of diagnostic and fault detection c i rcuits are incor porated to protect the drive. Some faults, like high DC bus and amplifier or motor over temperature, can be reset with the Reset button on the front of the d r ive or the R eset input functio n.
35 Diagnos tics and T ro ubleshootin g Fault Descrip tions Power Up T est This fault indicates that the power-up self-test has failed. This faul t cannot be reset with the reset co mmand or reset button . NVM Invalid At power-up the drive tests the integrity of the non-volatile memory.
36 Epsilon Eb Digital Ser vo Driv e Installati on Manual Invalid Configuration Ep silon Only This fault will occur if the digital board in the drive does not match the power board settings. It is only useful during manu facturing. A drive with this fault should be returned for serv ice.
37 Diagnos tics and T ro ubleshootin g Encode r State Certain encoder states and state transitions are invalid and will cause the drive to report an encoder state f ault. This is usually the result of noisy encoder feedb ack caused by poo r shielding.
38 Epsilon Eb Digital Ser vo Driv e Installati on Manual T ravel Li mit +/- This fault is caused when either the + or - Travel Limit input function is active. “All On” This is a normal condition during power up of the drive. It will las t for less than 1 second.
