explanations.

stopped, and relevant information will be listed on the monitor. When the problem is resolved, click <RESET>

button for detailed information. The display of a
caution will not interrupt the process of manufacturing, and it just reminds users the solution for certain
condition.
Operation alarm is decided along with the design of PLC LADDER. For example, if the protection door is not
well closed, the mechanism of LADDER will generate an alarm of
【
DOOR NOT CLOSE
】
, and the
malfunction of cooling water circulation for cutting will result in the message of
【
COOLANT LOW
】
, and so on.
Therefore, when an alarm occurs, carefully inspect the condition of the machine and peripheral equipments.
(This section is applicable to tool machine manufacturing personnel.)
The compilation of alarm messages is done by technician of tool machine manufacturing factories in
accordance with the designs of PLC LADDER, and considerations for machine operation. Users should not
change them discretionarily. When machines leave the factory, customers should be immediately informed of
the related instructions. The contents of these alarms should be compact and clear.
