Velocity dependent backlash

Recommended Posts

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?
