218/316 Bosch Rexroth AG | Tightening Technology 9 Tightening Processes9.2 Tightening program stepsExampleStart gradient calculation from the relative torque thresholdFigure 9–17:Gradient target function and relative torque thresholdIn Fig. 9–17, the absolute torque threshold is: 5 Nm + average value 13 Nm of the previous step = 18Nm.When the absolute torque threshold of Ts = 5 Nm (absolute: 18 Nm) is reached, gradient calculation tofulfill the Gradient = 0.1 Nm/° target function will be started.ExampleStart gradient calculation from the absolute torque thresholdFigure 9–18:Gradient target function and absolute torque thresholdWhen the absolute torque threshold of Ts = 18 Nm is reached, gradient calculation to fulfill the Gradient= 0.1 Nm/° target function will be started.9.2.3.6 Monitoring functionsThe monitoring functions include all the monitoring functions from the standard tightening step (seepage 214) and have additional, extended functions:– Relative torque– Torque max. value– Torque min. value– Torque average value– Torque range– Total angle– Gradient average value– Stick slip– Tightening, upper– Tightening, lower– Yield pointUp to 10 monitoring functions can be active simultaneously. Examples for parameter entry can be foundon page 219.9.2.3.7 Accept valuesThe data is taken over in the tightening program by selecting the Accept button. Data only becomes effectiveafter it has been sent to the controller!System 350 | 3 608 878 040/05.2008
