13.4 Automatic Operation Restart with BLOCK RESTART Condition
If the condition BLOCK RESTART
is switched on after returning to automatic mode
and than START button
is pressed, the control goes to the start position of the inter-
rupted block and continues machining from there, i.e., it re-executes the interrupted block.
This function is typically for the restart after tool break. After tool replacement the work zero
point offset values and/or tool compensation values can be changed. When pressing START
button it goes to the start position of the interrupted block with the new work and tool offset
values.
Its switch can be selected on OPERATOR’S PANEL or POSITION screens. After pressing
the action menu key,
F5
CONDITIONS must be selected, than
F5
BLOCK RESTART softkey
pressed. Afterwards the block execution is carried on according to the cases below.
If NCT machine control board is used select the
button.
13.4.1 Return to the Block Start Position by Means of Manual Operation
In the interrupted state (INTD) of automatic operation BLOCK RESTART
condition
can be switched on in any manual operation mode (Jog, Incremental jog, Manual handle feed).
After it is switched on the distance needed for return can be seen on the distance to go display
for each axis. The axes can be moved continuously in any (+/–) direction to the position, where
the distance to go is 0. The axis moved decelerates and stops automatically on the return
position. Afterwards the axis cannot be moved any more from this position, only if BLOCK
RESTART
condition is switched off.
There is no need to move fully to the return position, but by switching over to automatic mode
and pressing START
the return process can be continued. With the help of this function
return to start position can be made in the desired way, thereby avoiding the possible obstacles.
13.4.2 Return to Block Start Position in Automatic Mode
In automatic mode in case BLOCK RESTART
condition is on by the use of the START
button it returns to start position of the block by linear interpolation. If an obstacle is in the
way of the return, the movement can be broken with the help of STOP button. Afterwards the
return can also be continued by means of a manual mode.
