At the same time some global messages are also cleared from the message field of the status
bar.
The PLC program (generally) stops spindle rotation and suspends operation under execution.
Besides RESET key has other effects in the different modes as well.
In Automatic Operation in Case There is No INTD State Yet: If RESET key is pressed in
automatic operation and there is no INTD (interrupted) state yet, caption INTD is
displayed in the 3
rd
field of status bar. This means, that automatic operation is inter-
rupted. Afterwards program execution can be continued from the block, which has
been interrupted.
In Manual Data Input Mode: If RESET key is pressed in manual data input mode, program
execution is interrupted and it cannot be restarted from the interruption point, only
from the beginning.
In Case of the Execution of a Single Block: If RESET key is pressed during the execution of
a single block the block is cleared from the buffer. If the same block needs to be
executed again, the single block input must be terminated once more.
In case automatic mode is being selected, INTD state is in effect, no message is being
displayed in global message line and RESET key is pressed, INTD state is cancelled and the
program executor goes to the first line of the program selected for automatic execution, i.e.
machining begins from the beginning by pressing START button. INTD state is cleared and
control registers default status fixed at parameters.
10.4 Programmed Stop: M00
If control goes to code M00 during program execution, it executes block containing code
M00, than STOP state is assumed and the machining stops. With START button the
machining is continued.
10.5 Conditional Stop: M01
Conditional stop state can be
selected on OPERATOR’S
PANEL or POSITION screens.
After pressing the action menu

used select button.
If control runs to code M01
during program execution, it
