摘要:
A procedure for data transmission between a processing unit and a plurality of position measuring instruments, which are connected to one another in a linear bus topology. Generating a position data request signal from the processing unit and synchronously executing the position data request signal in the plurality of position measuring instruments.
摘要:
A method for serial data transmission between a position measuring system and a processing unit that includes transmitting a digital data word of defined length between the processing unit and the position measuring system and having a position data request signal arrive during the transmitting of the digital data word. Determining a position signal regarding a relative chronological position of the position data request signal with respect to the transmitted digital data word and transmitting the determined position signal to the position measuring system.
摘要:
A device for determining a signal running time between a position measuring system and a processing unit. The device includes first and second position signal generators that generate position signals regarding relative chronological position of a first running time measuring signal with respect to first and second data words. A first transmitter that transmits the first running time measuring signal and the first position signal to the position measuring system at the end of transmission of the first data word to the position measuring system. A second transmitter that transmits a second running time measuring signal and the second position signal to the processing unit after the end of transmission of the second data word. A timer that ascertains a length of time between transmission of the first running time measuring signal and reception of the second running time measuring signal by the processing unit and a signal running time generator that determines a signal running time from the length of time.
摘要:
A system that includes a position measuring device, a processing unit, a first data channel connecting the position measuring device to the processing unit and for transmitting data from the position measuring device to the processing unit and a second data channel connecting the position measuring device to the processing unit and for transmitting data from the processing unit to the position measuring device. Serial data transmission between the position measuring device and the processing unit is based on ethernet physics, wherein it is assured that a pickup of position data in the position measuring device always takes place at defined times and with the least possible chronological inexactness.
摘要:
A method for serial data transmission between a position measuring system and a processing unit that includes transmitting position data and further data between the position measuring system and the processing unit in serial form as digital data words, transmitting up-to-date position data between the position measuring system and the processing unit upon a position request command and always transmitting further data, whose processing is not time-critical, immediately following the up-to-date position data.
摘要:
A system for monitoring the temperature prevailing in the stator unit of an electric drive includes a temperature sensor that is integrated into the windings of the stator unit and that transmits a temperature-dependent sensor signal. The sensor signal may be injected via an electrical transmitter unit into the signal processing unit of a position measuring device connected to the drive.
