GuitarBrad Posted February 6, 2019 Share Posted February 6, 2019 I'm on a PMAC Mini (PMAC 1). I have a worm gear coupled to a motor via a flexible shaft adapter. I run with minimal blending, (I187=1, I188=0), and reverse the motor while it is rotating at varying velocities. The backlash introduced by the shaft adapter seems to vary with velocity. Does that mean I have to set up a backlash table, as opposed to just adjusting backlash iVars? Link to comment Share on other sites More sharing options...
curtwilson Posted February 20, 2019 Share Posted February 20, 2019 The backlash tables allow you to vary the magnitude of the backlash as a function of position, not velocity. So probably your best bet is to vary your backlash magnitude I-variable as a function of your velocity, probably in a PLC program. Link to comment Share on other sites More sharing options...
