62/316 Bosch Rexroth AG | Tightening Technology 6 Control Signals6.2 Tightening controllerIf the tightening channel was started as a single-channel tightening 1) , i.e. directly via the signals Cw or Ccw(e.g. in the ErgoSpin hand-held nutrunner), the results output is decoupled from the sequence end. Thismeans that the tightening channel can be restarted without a delay caused by results output. To accomplishthis, up to 16 results data records are buffered directly in the tightening controller's battery-bufferedmemory. If the memory is full, the sequence end is delayed until the memory is ready to receive data again.NoteResults output is not always completed after a sequence end for single-channel tightenings.If, after the evaluation of the PLC signals OK and NOK, the results data records must be clearly assignedto the tightening position, we recommend checking the results data records for plausibility. The plausibilitycheck can be done using the ID code or the consecutive number of the tightening.NoteThe PLC signals OK or NOK relevant for evaluating the tightening are available at the sequenceend CyCmp, independent of intermediate buffering.NoteDetails on the data output and its chronological order can be found in the individual chapters in Data Services.OK – OK (Tightening Result OK)Results description after a completed tightening process. This signal is statically present after a tighteninghas been ended. It is reset to “low” after a restart or a result reset (ResRs).NOK – NOK (Tightening Result Not OK)Results description after a completed tightening process. This signal is statically present after a tighteninghas been ended. It is reset to “high” after a result reset (ResRs) and to “low” after the start of the tighteningsequence.EStop – Emergency StopThis signal supplies information on the status of the XDN1 emergency OFF interface.If both emergency OFF circuits are closed, the signal switches to “high”.FtpF – FTP FaultThis signal reports an FTP signal error.ToolBn – Tool Button (Status of the Tool Button on ErgoSpin)This signal shows the status of the tool button on the ErgoSpin. Holding down the tool button keeps thesignal at “high”, releasing it changes the signal to “low”.CCwSel – Counterclockwise Select (Tightening Start Loosen Selected on ErgoSpin)NoteThis signal is only active in tightening channels with ErgoSpin!This signal changes to “high” when “Tightening start loosen” (program 99) has been selected using theCw/Ccw reversal switch on the ErgoSpin.NoteThe signal is only updated if a tightening job is not in progress!1) All tightenings with the CS351 Compact System are single-channel tightenings.System 350 | 3 608 878 040/05.2008
