12. Never attempt to use the M, S and T command in the overstored method.
13. Macro variable treatment
z
Polar coordinate interpolation (G12.1) macro statement, the macro program calling and the
block called by subprogram are regarded as attachment with sequence number, and therefore,
indexing this block will generate “Fail to find the specified sequence number or block number”
alarm. In this case, it is necessary the previous block only.
z
If the system variable operation generates during the index procedure, the alarm will then occur.
14. The selected program restarting operation is finish-turning shape block of the G71~G73, the
alarm will then issue.
6.5.4 Cautions
1. Principally, tool can not return to the correct position in the following situations:
It is essential to note that the alarm will not generate in the following conditions.
z
The manual operation can be performed in the manual absolute OFF.
z
When the manual operation is performed in the mechanical locking.
z
There is no coordinate system at the beginning of the program when the main command is
incremental method.
z
When the manual interference is performed during the axis movement of operation return.
z
When one block is specified a restarting program between the skip cutting block and the
subsequent absolute command block, when indexing the skip, it is retreated as the current skip
switch state.
z
When the mechanical locking is eliminated after the program restarting is specified in the
mechanical locking state.
z
When the block at the midway of the compound fixed cycle is specified the program restarting.
z
The coordinate system is set, changed and offset after the indexing is completed.
2. The cautions when the program used with macro variable is performed the program restarting
operation.
z
Common
variable
In the program restarting, the common variable uses the previous one instead of automatically
resetting. Therefore, the desired variable should be initialized as the value at the last automation
