Dear Experts i have CNC vertical lathe/milling machine with sinumerik 840D control. i have chuck or bed motor which works both lathe and milling mode. the problem is that in milling mode the chuck brake is not working according to our requirements(commissioning fault). the brake is controlled by plc output q60.5. now i want to create my own M command to On/Off this output. for example i enter M100 for activating Q60.5(means brake energized), use M101 for deactivating Q60.5(brake deenergized). i have no experience, how to add M commands in PLC program . I have STEP7 software and interface cable. i can online with 840D. i online searched all plc program to find any M commands to control this break but not successful. actually i have no idea how M commands are used in Plc Program. can u tell me how can i identify M commands in my plc program. what is the pattern of M commands in sinumerik 840D Plc.. i am an freelancer service engineer. so my tasks are below: 1- identify M commands in Plc program. 2- add user defined M commands for controlling an output. please help me out to resolve this issue. see attached plc ladder ..see FC121 Network 7 #out12(brake ouput) Thanks AttachmentPLC Ladder.pdf (298 Downloads) |
