Your questions are very hard to answer in this forum. I can answer you one important. then tell you how to know others. Q--"Why can't only plc be used for cutting and drilling application why special controller 840d is required???. A--" Most important function for CNC controller --is That it can control "interpolation" --simply saying it can control 2 or 3 axes up to 5 axes working together coordinated --to cut a curve in the plane or in the space. PLC can really control drilling machine, which does not need interpolation. do you notice --even PLC can control more axes,--these axes can move at the same time, but they are no relationship to each other. Now other questions, ---If you want to learn the basic of CNC---Google or Youtube ---If you want to know Siemens Sinumerik --search "DoconWeb" --ready by yourself. ---If you feel reading by yourself is hard --try to joint some online training courses, or visit Siemens training center I attached one of Manual for 840D Powerline If you want to get some training sources , you can PM me

Hello Pankaj
840D communicates with 611D drive via drive bus X131/X341. 611D drive has control module & LT power module. Control module is selected depeding upon application performnace & interface while power module is selected depending upon motor connected i.e. load requirement. For more detail information please refer SINUMERIK 840D, SIMODRIVE 611D, SINUMERIK 840D, SIMODRIVE 611 digital
PLC CPU is integrated in 840D NCU. NCU is selected depending upon application type, number of axes controlled, any special option/feature to be incorporate, other opetions like gantry, master slave or compensastions to be activated etc. etc. As per NCU pre configured PLC CPUs are intergrated in NCU. For more details please refer NCU,
User can connect & control 6RA70 DC drive by 840D system either via Digital input & outputs or via network. In network more data transfer & communication is possible/available where as via DI/DO only limited control/communication is possible.
NC i snumerical controller which was way before CNC. With latest computer automation CNC controllers has replaced NC controllers due to their advantages like, much faster speed/communication with other,automation systems, multitask processors, can handle more channels simultenously etc. etc. For simple drilling, cutting application pre programed PLC or system like SIMOTION (in Siemens) is available. Experts can select the correct controller & drives as per application requirement. For critical applications CNC systems are selected. HTH. P. S. - With my limited knowledge I tried to explain you basic concepts. Let us hope, other member/expert from forum may share other more technical information. |
