16.4.5 Intermediate gearApplication and functionsA configured intermediate gear can be used to adapt a variety of rotating tools. Theintermediate gear on the tool side has a multiplicative effect on the motor/load gearbox.It is set via machine data:MD31066 $MA_DRIVE_AX_RATIO2_NUMERA (intermediate gear numerator)MD31064 $MA_DRIVE_AX_RATIO2_DENOM (intermediate gear denominator)An encoder on the tool for the intermediate gearis configured with machine data:MD31044 $MA_ENC_IS_DIRECT2 (encoder on intermediate gear).Change parameters for this machine data can be activated with "NewConfig" either using theSinuCOM-NC commissioning software or via a softkey on the operator panel (HMI). Theexisting motor/load gearboxes, on the other hand, are active after POWER ON.Tool changeIf the intermediate gear is changed at the same time as the tool, the user must also reconfigurethe transmission ratio of the numerator and denominator via the machine data of theintermediate gear.Example:CAUTIONEngineering errorIt remains the task of the user to stop within the appropriate period in order to make changesto the machine data when required and then activate a "NewConfig".In the case of an installed tool with a transmission ratio of 2:1, a suitable intermediate gear isconfigured and is activated immediately in the part program with the command NEWCONF.Program codeN05 $MA_DRIVE_AX_RATIO2-NUMERA[AX5] = 2M10 $MA_DRIVE_AX_RATIO2-DENOM[AX5] = 1N15 NEWCONFS1: Spindles16.4 Configurable gear adaptationBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 1249
