Epsilon Eb and EN Drives Reference Manual

Fault Codes

A number of diagnostic and fault detection circuits are incorporated 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 drive or the Reset input function. Other faults, such as encoder

faults, can only be reset by cycling power “Off” (wait until the status display turns “Off”),

then power “On”.

The drive accurately tracks motor position during fault conditions. For example, if there is a

"Low DC Bus" fault where the power stage is disabled, the drive will continue to track the

motor’s position provided the logic power is not interrupted.

The +/- Travel Limit faults are automatically cleared when the fault condition is removed.

The table below lists all the fault codes in priority order from highest to lowest. This means

that if two faults are active, only the higher priority fault will be displayed.
