B. Allowable Load Inertia
The table below displays the maximum inertia ratio (load inertia/motor inertia) of the
-
load, which can be attached in each motor. It is based on the regenerative energy
absorbable in the capacitor (during deceleration) at the horizontal load.
When operating the load larger than the allowable load inertia, connect a regeneration
-
resistor or auxiliary capacitor.

Above inertia is the maximum value thus use with sufficient allowance.
When connecting a load larger than the allowable load inertia, connect a
!
regeneration resistor, regeneration unit or auxiliary capacitor.
Warning
When connecting a load larger than the allowable load inertia and using
repeatedly, electrolytic capacitor may be damaged or the lifespan of the drive
may be reduced.
