TB267 (Rev4)-CNC11 Yaskawa Sigma5 Precision Mode SetupOverview:This document will walk you through the process of configurating and tuning a Yaskawa Sigma VServo Drive Pack and motor with a centroid CNC11 based control,running in Precision Mode.Centroids Precision Mode can provide very good resolution and high feedrates,but the following maximums should not be exceeded:MPU11 max Counts/min 72,000,000This maximum is derived from the maximum counts per interrupt 300 counts/int 4000 int/sec 60secondsDrive max command counts per second that the drive can accept (1,200,000/sThe following table shows examples of resolutions resulting from selected encoder counts per rev andballscrew pitch.Encoder Counts/Rev Yielding Resolution and Speeds.12mm PitchCounts/RevResolutionMaxRPMMax SpeedMax Speed("/Count)(/Min)(mm/Min)81920.0000588789415249828163840.0000294395207624914See Notes*240000.0000203000141717008327680.000014219710381245716mm PitchCounts/RevResolutionMaxRPMMax SpeedMax Speed("/Count)(/Min)(mm/Min)81920.0000778789553688583163840.0000384395276844291See Notes*240000.0000263000189030236327680.0000192197138422146*Yaskawa Sigma Series 5 Motors(SG-MGV)Maximum RPM=3000The 8192 default value referred to in the Tech Bulletin and manual refers to 8192 lines=32768countsper rev.
