APR Faults
APR faults are generated during the events and when one of the conditions
that are defined in the following APR Fault Conditions
is present.
APR Fault Conditions
The axis must be in the homed state for an APR Fault to occur. The Axis
Homed Status Bit must be set.
Attribute Changes
A Motion Resolution or an Axis Feedback Polarity attribute has been changed
and downloaded to the controller. This change can also happen during the
execution of an SSV.
Axis Feedback Changes
The feedback device has been replaced. This change creates an Axis Feedback
Serial Number mismatch APR fault.
Axis Feedback mode has changed, for example, axis with feedback changed to
axis without feedback or vice versa and downloaded to the controller.
• A user program is downloaded.
• A user program and tags are restored from the memory card.
–Manual Restore
– Power-up restore, when configured
• Firmware is updated via ControlFLASH software.
• An SSV to either change Feedback Polarity or one of the attributes,
which results in a change to the Motion Resolution attribute.
