6 Control Signals Tightening Technology | Bosch Rexroth AG 59/3166.2 Tightening controllerIf the hand-held nutrunner function, and thus the function Play at start switch, is active in the channelconfiguration, a tightening start is not considered performed if the maximum occurring torque remainedbelow the defined torque threshold 1) . The controller performs no evaluation (OK/NOK) and no results output.If the program is invalid (not programmed or incorrectly programmed), the sequence end is immediatelysignaled, in connection with a system error.NoteSpeed monitoring is not performed when program no. 47 is started!Ccw – Counterclockwise (Tightening Start Loosen)Program no. 99 loosen starts.NoteNo zero point test is done when program no. 99 is started with the signal Ccw!ResRs – Reset Result (Result Reset)We recommend resetting the results before every restart. Please also observe the sequence on page 66.ResRs = “high”– sets the signals CyCmp, OK, the PLC signals of the monitoring functions, e.g. TorqH, and TrigOutto “low”, and the NOK signal to “high”.– deletes the ID code in the input buffer.NokAc – NOK Acknowledge (NOK Acknowledgement)The tightening system also provides you with an option to prevent further starts after an NOK tightening.A restart is only possible after the NokAc signal has been set to “low”.This function is active if the signal NokAc is set to “high” at the defined starting point. The tightening systemis ready to start again when the NokAc signal has been set to “low” after an NOK tightening. Thesystem is ready to start when the InCy signal is shown as “low”.NoteIf NokAc is assigned to input 0.3 in the PLC table of a tightening channel with ErgoSpin, the signal isinverted, i.e. the signal switches to “low” when the ErgoSpin tool button is pressed, and to “high” whenthe tool button is released.DisRp – Disable Report (Disable Results Output)This input (input at “high”) can be used to suppress the results output for the subsequent tightening sequence,in order to be able to run “hidden” processes. Results data output via FTP, printer, and Profibusis suppressed. Evaluations and outputs via the BS350 and CS351 display are not suppressed.DisRpFtp – Disable Report FTPResults output with FTP can be suppressed via this input.UsrIn 1– User Input 1 (External Input Signal 1)This signal can be used as an external input signal for program functions, e.g. in “Target function input”or “Conditional input branch”.UsrIn 2– User Input 2 (External Input Signal 2)See the previous section.1) This threshold can be set in the start step of the tightening program. The default value is 5% of thenominal torque of the spindle. It is active if the additional functionality Hand-held nutrunner has beenactivated in the channel configuration.System 350 | 3 608 878 040/05.2008
