5.5.5 Limit of Inertia Ratio
Please see the limit of inertia ratio below during the estimation.

Acceleration / Deceleration time of reaching 2000 r/min should be less than 1 second.

The speed in forward and reverse direction should be higher than 200 r/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 and set P2-32 to 2. Then, Servo on
again.
Set P0-02 to 15. The panel
displays The inertia ratio*.
The servo drive issues the
command and to make motor
alternately accelerate /
decelerate.
Any
resonance?
Satisfactory
performance?
Increase the value of P2-31
to increase response and
stiffness.
If the value of inertia ratio
remains almost the same, then
servo off and set P2-32 to 0.
1. Lower the value of P2-31 to reduce the noise.
2. If not desire to lower the value of P2-31, value
of P2-23 and P2-24 can be used to suppress the
resonance as well.
