Motor encoder (encoder1) has been interfaced in CU310dp and another encoder (encoder2) fitted in an idle roller for detecting line speed has been interfaced with smc30. 2. Now in DCC, technology function for diameter calculation requires line speed. 3. If I would get the rpm of the idle roller from encoder2, I could find out the line speed. But in which parameter can I get the rpm from encoder2? Best regards, Shyamal

I have already collected DCC winder application v3.0.0 along with sinamics dcc v2.1 for starter v4.2 (6au1810-1ha21-0xa0). 1. Now I want to configure two pm340 with cu310dp - one for winder and other for unwinder with indirect tension control mode. 2. If I link p21515 (actualweb velocity) to an web encoder for calculating diameter (Function diagram WI1100),where will I link reference line speed? 3. The reference line speed is supposed to be converted actually into motor rpm (of both unwinder and rewinder) from gear ratio and diameter. But at the starting time whentension is just on and diameter is yet to be started to calculate, how will motor rpm be calculated from line speed? 4. Whatare the functions of maneuvering parameters p21619 and p21620 (Function diagram WI1110.1)? I will very grateful if you kindly explain me the above points. Best regards, Shyamal

They confirmed that this application needs a separate speed master. Winder / Unwinder configured with this application will take reference speed from that master or from the web encoder for diameter calculation and subsequently winder speed reference. However, as in my case it is a roll to roll winding which means that one roll is for winding and other for unwinding, is it possible to configure winder as speed master (updating cyclically its speed reference from the calculated diameter) and unwinder as tension controller (as if, it is an externally mechanical brake-controlled roll). Any idea, experience in this type of configuration, suggestions will help me much. thank you, Best regards, Shyamal

To get rid of this problem, I need your valuable suggestions / helps. Please refer to Function diagram WI1010 and WI1030 of Sinamics DCC for winder Version 3.0.0. In the function diagram WI1030, there is one AND gate of 5 (five) inputs -1. STW winder tension operation, 2. Enable tension operation from synchronization, 3. SW sequence control operation enabled, 4. inverted SW winder web break and 5. inverted rewinding splice break. Diameter calculation will not be enabled unless the output of this AND gate is true. Input no. 3, control operation enable, bit2 of internal status word of drive, will be high when the drive will follow N_set (Sinamics S Function diagram 2503). Again web break bit of status word of winder (bit9, function diagram WI1020 of DCC) will be high when the drive runs at torque limit (that means, in this case, drive does not follow the set speed N-set. Then, how will these two signals be such simultaneously that the above AND gate output can be high. Best regards, Shyamal

It will be highly be appreciable if you kindly give me some more informations: 1. Is there any input in this AND gate which is true only when the drive will operate in torque limit? 2. I think 4th input, "inverted web break", is probably this kind of input. 3. I am confused with the first input, "tension operation" (bit2 of internal status word of winder), about how it becomes true. If being the output of this AND gate true requires that the drive must be operated in torque limit, the diameter calculator in this application can not be enabled if the the drive is configured in speed controlled mode. Is there any way? Best regards, Shyamal
