Always set the stored stroke limit. Setting no limits could result in collision with the
machine end.
Always turn the power OFF before connecting/disconnecting the input/output device
cables. The NC and input/output device could be damaged if the cable is connected
in the power ON state.
If the tool compensation amount is changed during automatic operation (including
single block stop), the amount will be validated from the next block or several blocks
following.
If the workpiece coordinate offset amount is changed during single block stop, the
changes will be valid from the next block.
Pay close attention to the sequence operation when carrying out forced data setting
(forced output) in the PLC I/F (diagnosis) screen.
If the operation start position is set from a block in the program and the program is
started, the program before the set block is not executed. If there are coordinate
system shift commands or M, S, T, and B commands before the block set as the
starting position, carry out the required commands using the MDI, etc. There is a
danger of interference with the machine if the operation is started from the set starting
position block without carrying out these operations.
To prevent the influence of data loss and data transformation over the line, always
carry out data comparison after transferring a machining program.
Do not change the setup parameters without prior consent from the machine
manufacturer.
If there is no value after the G command, the operation will be the "G00" operation
when the program is run due to key chattering, etc., during editing.
" ; " "EOB" and " % " "EOR" are symbols used for explanation.
The actual codes are: For ISO: "CR, LF", or "LF" and "%".
Programs created on the Edit screen are stored in the NC memory in a "CR, LF"
format, but programs created with external devices such as the FLD or RS-232C may
be stored in an "LF" format.
The actual codes for EIA are: "EOB (End of Block)" and "EOR (End of Record)".
When creating the machining program, select the appropriate machining conditions so
as not to exceed the machine and NC performance, capacity and limits. The examples
do not consider the machining conditions.
Do not change the fixed cycle program without prior consent from the machine
manufacturer.
Do not enter the movable range of the machine during automatic operation. Make
sure not to place hands, legs or face near the spindle during rotation.
Always carry out dry run operation before actual machining, and confirm the machining
program, tool offset amount and workpiece coordinate system offset amount.
