5.AUTOMATIC OPERATION B-63783EN-1/01
- 506 -
Limitation
- Automatic reference position return
The command for automatic reference point return (G28 and G30) in
the cutter compensation mode does not return the tool to the correct
position even when the restart operation is performed within the block.
-Dwell
The restart operation cannot be performed in the block for which a
dwell (G04) has been specified.
- Setting a compensation value
The compensation value must be set prior to turning on the block return
switch.
- In three-dimensional cutter compensation mode
In the three-dimensional cutter compensation mode with zero value,
suppose the tool movement is interrupted, the compensation value is
changed, and the operation is restarted. In this case, the vector for the
cutter compensation is not recalculated.
Note that if the compensation values are changed excessively, the
accuracy for vector calculation may deteriorate.
- Cycle start ignored
When the block return switch is on, if the message RSTR does not
appear on the CRT screen, the cycle start command is ignored.
- When the block return switch status is changed
Operating the block return switch during continuous manual feed stops
the tool.
- Block containing no move command
Operation must not be restarted in a block without a move command.
- Restart after single-block stop
After a single-block is stopped, operation is restarted at the block after
the block that has already been executed by the single-block function.
