5.6.5 Limit of Load Inertia Estimation
Acceleration / 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-auto
mode, the inertia value will be saved to P1-37 only until the system inertia is stable and
stops the estimation of load inertia.
Servo Off. Set P2-32 to 2 and then Servo On.
Set P0-02 to 15. The panel
displays inertia ratio.
The servo drive issues the command of
alternately accelerate /decelerate.
1. Decrease the value of P2-31 to
reduce the noise. Set P2-25
according to the new value of P2-
31.
2. If users do not want to
decrease the value of P2-31, P2-
23 and P2-24 can be used to
suppress the resonance as well.
(Please refer to Chapter 5.6.6.)

If the value of inertia ratio remains
almost the same, then Servo Off and
set P2-32 to 0.
