Fault Codes
A number of diagnostic and fault detection circuits are incorporated to protect the drive. Some faults, such as High DC Bus
and 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 diagnostics 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.
