Speed setpoint matching can be performed automatically ormanually.It is possible to perform automatic speed setpoint matching if the drive supportsacyclic services on the PROFIBUS DPAcyclic services on the PROFIBUS DP are supported by the followingSIMODRIVE drives:– SIMODRIVE 611 universal/E– SIMODRIVE POSMO CD/CA– SIMODRIVE POSMO SIand the value 0 must be entered in machine data: MD32250: RATED_OUTVAL (rated output voltage) [ % ]During start-up of the NC, speed setpoint matching between the NC and thedrive is then performed automatically.NoteIf automatic speed setpoint matching fails for one axis, the following messageis output on a traverse request for his axis: Message “Wait, axis enable missing”This axis and any axes that interpolate with it are not traversed.If a value not equal to 0 is entered in machine data MD32250: RATED_OUTVAL (rated output voltage) [ % ]the NC assumes that speed setpoint matching will be performed manually.The rated motor speed entered in axis-specific matching data: MD32260: RATED_VELO (rated motor speed) [ rev/min ]with reference to 100% must be equal to the speed evaluation entered in thedrive (P880): P880: Speed evaluation PROFIBUS [rpm] (ARM/SRM) or[ m/min ] (SLM)MD32260: RATED_VELOP880SINUMERIK 840Di-NC SIMODRIVE 611 universal.* 100 =MD32250: RATED_OUTVALAutomaticmatchingManualmatchingSIMODRIVE611 universal/EPOSMO CD/CAPOSMO SI10 NC Start-Up with HMI Advanced
