Page 356: Interconnecting Signals In The Converter
Appendix A.2 Interconnecting signals in the converter Interconnecting signals in the converter A.2.1 Fundamentals The following functions are implemented in the converter: • Open-loop and closed-loop control functions • Communication functions • Diagnosis and operating functions Every function comprises one or several blocks that are interconnected with one another. Figure A-1 Example of a block: Motorized potentiometer (MOP) Most of the blocks can be adapted to specific applications using parameters.
Page 357 Appendix A.2 Interconnecting signals in the converter Binectors and connectors Connectors and binectors are used to exchange signals between the individual blocks: • Connectors are used to interconnect "analog" signals (e.g. MOP output speed) • Binectors are used to interconnect digital signals (e.g. "Enable MOP up" command) Figure A-3 Symbols for binector and connector inputs and outputs Binector/connector outputs (CO/BO) are parameters that combine more than one binector...

Page 359 Appendix A.2 Interconnecting signals in the converter Explanation of the application example using the ON/OFF1 command Parameter p0840[0] is the input of the "ON/OFF1" block of the converter. Parameter r20031 is the output of the AND block. To interconnect ON/OFF1 with the output of the AND block, set p0840 = 20031.
