90 Program featuresMiscellaneous User parameter setsThe drive supports four user parameter sets that can be saved to the permanentmemory and recalled using drive parameters. It is also possible to use digital inputs toswitch between user parameter sets.A user parameter set contains all editable values in parameter groups 10…99 except• forced I/O values such as parameters 10.03 DI force selection and 10.04 DI forcedata• I/O extension module settings (groups 14…16)• fieldbus communication enable parameters (50.01 FBA A enable and 50.31 FBAB enable)• other fieldbus communication settings (groups 51…56 and 58)• encoder configuration settings (groups 92…93), and• some hardware settings in parameter group 95 HW configuration.As the motor settings are included in the user parameter sets, make sure the settingscorrespond to the motor used in the application before recalling a user set. In anapplication where different motors are used with the drive, the motor ID run needs tobe performed with each motor and the results saved to different user sets. Theappropriate set can then be recalled when the motor is switched.If no parameter sets have been saved, attempting to load a set will create all setsfrom the currently active parameter settings.SettingsParameters 96.10…96.13 (page 416). Parameter checksum calculationA parameter checksum can be calculated from a user-definable set of parameters tomonitor changes in the drive configuration. The calculated checksum is compared to1…4 reference checksums; in case of a mismatch, an event (a pure event, warning orfault) is generated.By default, the set of parameters included in the calculation contain most parameterswith the exception of• actual signals• parameter group 47 Data storage• parameters that are activated to validate new settings (such as 51.27 and 96.07)• parameters that are not saved to the flash memory (such as 96.24…96.26)• parameters that are internally calculated from others (such as 98.09…98.14).• dynamic parameters (eg. parameters that vary according to hardware), and• application program parameters.The default set can be edited using the Drive customizer PC tool.ghv Vertriebs-GmbH | Am Schammacher Feld 47 | 85567 Grafing | Telefon + 49 80 92 81 89 0 | info@ghv.de | www.ghv.de
