sathya_sha Posts: 9 Rating: (1)	am using a SPINNING machine with 840d controller. 4axis in single channel. X,Y and U axis are Spinning Roller axis and Z axis is for Feed. I have configured one Digital Input.10 in the PLC program. My Issue is During spinning all the XYZ axis are in set extended poistion and Z axisin feed(20mm). When the digital input 10 goes High state then Z axis feed should stop and XYZ Axis should retract to the set position. I have written the Part program such that for every 0.250mm, condition statement(IF $input(10)==1 GOTO ......) is checked. The Part Programhas become very lengthy. I have tried WHENEVER command it not works. As i am not familiar with the Part programs. is there any command for simple Programming Thanks RSN

N2 IDS=1 EVERY $A_IN[1]==1 DO M70 regards Ram Attachment synchronous action.pdf (180 Downloads)
