- Restrictions on resumption of automatic operation
(1) Resuming a program
Curve interpolation is performed for corrected insertion points
not for programmed points in the nano smoothing mode.
Accordingly, when a sequence number is specified to resume the
program, the operation cannot be resumed from a programmed
point in a block.
To resume a program, specify a block number, using the block
counter displayed in the program screen.
(2) Resuming a block
A block cannot be resumed in the nano smoothing mode. When
an attempt is made to resume a block, a P/S alarm No. 344 will
be issued.
(3) Retracting and returning the tool
The tool cannot be retracted or returned in the nano smoothing
mode.
(4) Retracing
Retracing cannot be performed in the nano smoothing mode.
(5) Active block cancel
The active block cancel function is temporarily disabled in the
nano smoothing mode.
- Functions that cannot be used simultaneously
The nano smoothing function cannot be used simultaneously with the
following functions.
• Parallel axis control
• Twin table control
- Background graphic display
The background graphic display function draws the path in the nano
smoothing mode by linear interpolation.
Parameter
8486
Maximum travel distance of a block where smooth interpolation or Nano
smoothing is applied
[Input type] Setting input
[Data type] Real path
[Unit of data] mm, inch (input unit)
[Minimum unit of data] Depend on the increment system of the reference axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting
table (A) )
(When the increment system is IS-B, -999999.999 to +999999.999)
This parameter specifies a block length used as a reference to decide
whether to apply smooth interpolation or Nano smoothing. If the line
specified in a block is longer than the value set in the parameter,
smooth interpolation will not be applied to that block.
