  1. Getting cam derivation values

    Hello, So my intention is to create dynamic camdics at runtime. In that program I have introduced a feedback to verify the follower position ,velocity and acceleration values are matching with parameters I have given whilst determining the polynomial coefficients.  I am using the command _getCamFollowingDerivative to get the derivates of the 1st and 2nd order (Velocity and Acceleration values respectively) of the segments. In one of the segments (4th) I am getting one the velocity values mismatched. I am confused, why am I getting the velocity as incorrect. Please refer to the attachment below  
  2. PID I & D Unit

    Hi All,  I need some clarification on the PID instruction. The note states that if #9 is set for C+6 04-07, the I & D will be 0.1 to 819.1s. But I didn't understand this highlighted section. Does it mean that my I and D values will something between  (1x τ)~(8191xτ)s??   All help is much appreciated, Stay safe and healthy. T J Sharon
