6 Control Signals Tightening Technology | Bosch Rexroth AG 63/3166.2 Tightening controllerCheckEs – Check ErgoSpin (ErgoSpin Test Interval Reached)This signal switches to “high” once a test interval set in the channel configuration has been reached usingthe ErgoSpin, e.g. a particular test date or a defined cycle counter state has been reached. The signal isset to “low” if monitoring is deactivated or if the test interval is reset. The signal is updated approximatelyevery 20 seconds.CntOK – Counter OK (Default Value of the OK Counter Reached)This signal changes to “high” if the set default value of the OK counter has been reached. The tighteningchannel can be optionally blocked when the OK default value has been reached.CntNOK – Counter NOK (Default Value of the NOK Counter Reached)This signal changes to “high” if the set default value of the NOK counter has been reached. The tighteningchannel can be optionally blocked when the NOK default value has been reached.This signal is also set if the counter record is changed before reaching the OK or NOK counter value andan attempt has been made to start a tightening. In this case, the start will not be accepted (exception:loosening program no. 99 can be started).RC0-4 – Rework Code Bit 0-4The binary encoded rework code is output via these five output signals. A rework code can be used toinform the user of the necessary steps to rework a tightening that has been evaluated as NOK (e.g. as atext on the TFT display or as a number on the LC display).These signals are set at the end of a tightening; they change to “low” at the start of a tightening and whenthe “Reset result” signal is set.TrigOut – Trigger Out (Trigger Output)Using the trigger output function, the PLC output TrigOut is created as soon as the set condition hasbeen reached. The output is reset during the next program start or by the signal ResRs. The followingtrigger conditions can be defined in the extended tightening step (Xt tightening step):– Start angle counting– Step start– Target function reached.TorqH – Torque Too HighResults description after a completed tightening process. The torque is above the defined tolerance window.TorqL – Torque Too LowResults description after a completed tightening process. The torque is below the defined tolerance window.AnglH – Angle Too HighResults description after a completed tightening process. The angle is above the defined tolerance window.AnglL – Angle Too LowResults description after a completed tightening process. The angle is below the defined tolerance window.GradH – Gradient Too HighResults description after a completed tightening process. The gradient is above the defined tolerancewindow.GradL – Gradient Too LowResults description after a completed tightening process. The gradient is below the defined tolerancewindow.System 350 | 3 608 878 040/05.2008
