---- Basic and necessary programming ----
( ) = /STOP
Permission to execute the part-program
() = /FEEDHOL
Permission to move the axes
( ) = /XFERINH
Permission to execute the next block
I-EMERG AND (rest of conditions) = /EMERGEN
If the external emergency input is activated or any other emergency occurs, the general logic input
/EMERGEN of the CNC. When there is no emergency, this signal must remain high.
/ALARM AND CNCREADY = O-EMERG
The emergency output, O1, of the PLC (O-EMERG) must be normally high
If an alarm or emergency is detected at the CNC (/ALARM) or a problem was detected when
powering the CNC up (CNCREADY), the emergency output O-EMERG must be brought low.
I-CONDI = M01STOP
When the operator selects the conditional mode (I-CONDI), the CNC general logic input M01STOP
must be activated. It interrupts the program when executing M01.
START AND (rest of conditions) = CYSTART
When the cycle START key is pressed, the CNC activates the general logic output START.
The PLC must check that the rest of the conditions (hydraulic, safety devices, etc.) are met before
setting the general input CYSTART high in order to start executing the program
SERVO-OK AND NOT LOPEN = SERVO1ON = SERVO2ON = SERVO3ON
If the servo drives are OK and the CNC does not detect any errors in the positioning loop of the axes
(LOPEN), the positioning loop must be closed on all axes. Axis logic inputs of the CNC: SERVO1ON,
SERVO2ON, SERVO3ON.
