ASDA-M Chapter 5 Trial Operation and TuningRevision December, 2014 5-175.6.5 Limit of Load Inertia EstimationAcceleration / Deceleration time of reaching 2000r/min should be less than 1 second.The speed in forward and reverse direction should be higher than 200r/min.The load inertia should be under 100 times of motor inertia.The change of external force of inertia ratio cannot be too severe.In auto mode, the inertia value will be saved to P1-37 every 30 minutes; while in semi-automode, the inertia value will be saved to P1-37 only until the system inertia is stable andstops the estimation of load inertia.Servo Off. Set P2-32 to 2 and then Servo On.Set P0-02 to 15. The paneldisplays inertia ratio.The servo drive issues the command ofalternately accelerate /decelerate.1. Decrease the value of P2-31 tor e d u c e t h e n o i s e . S e t P 2 - 2 5according to the new value of P2-31.2 .
