90313, Enable 1 supervision fault
Description
The Enable 1 circuit has been broken. This circuit monitors the
function of the safety system and the main computer.
Consequences
The system goes to status SYS HALT.
Probable causes
A fault, probably a software fault, has been detected by any of
the units supervised by the Enable 1 circuit.
Recommended actions
Attempt restarting by pressing the Motors ON button. If
restarting is IMPOSSIBLE it indicates a possible hardware fault.
If restarting is POSSIBLE, it indicates a software fault. In such
case, contact your local ABB representative. Determine which
unit is faulty by checking its indication LEDs. The LEDs are
described in the Trouble Shooting Manual. Replace the faulty
unit.
90314, Enable2 supervision fault
Description
The Enable 2 circuit to drive module 1 has been broken. This
circuit monitors e.g. the function of the safety system and the
axis computer.
Consequences
The system goes to status SYS HALT.
Probable causes
A fault, probably a software fault, has been detected by any of
the units supervised by the Enable 2 circuit.
Recommended actions
Attempt restarting by pressing the Motors ON button. If
restarting is IMPOSSIBLE it indicates a hardware fault in safety
system, axis computer. If restarting is POSSIBLE, it indicates
a software fault. In such case, contact your local ABB
representative. Determine which unit is faulty by checking its
indication LEDs. The LEDs are described in the Trouble
Shooting Manual. Replace the faulty unit.
90315, Enable2 Supervision fault
