摘要:
A method for axis correction in a processing machine, in particular a shaftless printing machine, has at least one axis for processing and/or transporting a material, at least one detection device for detecting a processing parameter and at least one controller device for calculating a controller output variable for axis correction of the at least one axis using the detected processing parameter. The method is implemented iteratively, with the result that feedforward control output values for the feedforward control of the axis correction are determined during an (n+1)-th change in rotation speed of the at least one axis using observation of the controller output variable and/or the processing parameter during an n-th change in rotation speed of the at least one axis.

The present invention relates to a method for transmitting multiturn modulo control axis data which includes at least one control axis position value (600°-604°; 245°-248°) and an associated control axis modulo value (720°; 360°) in one communication system which includes at least two participants, at least one real-time data transmission channel (CH1) being provided for the cyclic transmission of data between the participants; the at least one control axis position value (600°-604°; 245°-248°) is transmitted together with the associated control axis modulo value (720°; 360°) in one data telegram (22; 33).
摘要:
In a method for axial correction in a processing machine (100), which has at least two driven transport axles (110, 115) for transporting and processing a product web (101), at least one non-driven or driven processing axle (111, 112, 113, 114), and at least one additional non-driven axle (102, 121, 122, 123, 124), wherein the product web (101) is divisible into at least one web-tensioning segment, a web-tensioning segment is delimited by two clamping points (110-115). The clamping points are embodied in the form of driven transport or processing axles. During a rotation speed change of a clamping point (110-115) a web-tensioning segment is delimited, a pilot control of this clamping point (110-115) delimiting the web-tensioning segment and/or of a processing axle (111-114) situated in this web-tensioning segment is carried out, taking into account a moment of inertia of a non-driven axle (102, 121-124) situated in this web-tensioning section, and a corresponding processing machine (100).
摘要:
The invention relates to a method for determining at least one controller parameter of a control element in a web tension control circuit for a processing machine for processing a web of material, in particular a shaftless printing press. The at least one controller parameter is determined as a function of at least one parameter characterizing the web of material, at least one parameter characterizing the processing machine, and at least one idle time.
