14 Listing of Messages and their Codes
122
Messages of custom macros:
– error messages programmed by the user and waiting for to be canceled, or
– messages programmed by the user waiting for START.
In the case of global messages the different messages are needed to be answered differently,
i.e., to be canceled. Therefore, in the enclosed table after each message the method of cancel-
ing it is shown. These may be as follows:
Canceling message by means of turning power off and on
In case of extremely serious or dangerous alarms the message cannot be canceled, the NC must
be restarted. These messages cut the machine off the NC and create emergency stop (EMG)
state every time.
Canceling message by means of pressing RESET key
This is the general mode of canceling error messages. By the use of the RESET key the
automatic execution is interrupted. If thereafter the START button is pressed, the NC pre-
processes the block and if the error has been repaired successfully it also re-executes the block.
In case of extremely serious or dangerous alarms the message cuts the machine off the NC,
creates emergency stop (EMG) state and deletes the reference point. After using the RESET
button, the machine can be turned on. Than the machine must be returned to the
reference point.
Canceling message by means of pressing START button
As the effect of certain messages displayed by the PLC program or custom macro messages
written by the user the control assumes STOP state and waits for the operator’s intervention in
accordance with the message. After the wished operation has been done by the operator the
machining is continued by means of START button .
Canceling message by means of operator’s intervention
Certain messages can only be canceled by ceasing the reason of their appearance. This is the
situation in the case of message LIMIT X+, which can only be canceled, if the limit switch is
left behind by moving in negative direction in a manual mode.
