4. Limitations
D Restart
Under any of the following conditions, restart cannot be performed:
S When automatic operation has not been performed since the power was turned on
S When automatic operation has not been performed since an emergency stop was released
S When automatic operation has not been performed since the coordinate system was changed or
shifted (change in an external offset from the workpiece reference point)
D Restart Block
The block to be restarted need not be the block which was interrupted;
operation can restart with any block. But the restart block must use the same coordinate system as
when operation was interrupted.
D Single block
When single block operation is ON during movement to the restart position, operation stops every time
the tool completes movement along axes. When operation is stopped in the single block mode, MDI
intervention cannot be performed.
D Manual intervention
During movement to the restart position, manual intervention can be used to perform a return opera-
tion for axis if it has not yet been performed for the axis. A return operation cannot be done further on
axes for which a return has already been completed. And move command cannot be specified from
the MDI panel during a restart operation.
D Reset
Never reset during the time from the start of a search at restart until machining is restarted. Otherwise,
restart must be performed again from the first step.
D Manual absolute
Regardless of whether machining has started or not, manual operation must be performed when the
manual absolute mode is on.
D Reference position return
If no absolute–position detector (absolute pulse coder) is provided, be sure to
perform reference position return after turning on the power and before performing restart.
D Moving the axis on MDI mode after searching the block number
After searching the block number, it is impossible to move the axis on MDI mode such like “Macro Call
Command” with M/T/G–code or “Axis Control by PMC” function. It is possible to move the axis with
manual handle or Jog operation only.
If the operator wants to move the axis on MDI mode, please move it before searching the block number
surely.
Be sure to set the following parameter No. 3407.
#7 #6 #5 #4 #3 #2 #1 #0
3407 C14
By resetting on the CRT/MDI panel, the G code of group number 14 is:
C14 = 0 : Cleared.
= 1 : Not cleared.
Be sure to set 1.
