Load Inertia Ratio
Sets the ratio between motor inertia and machine inertia.
1.0
(0.1 - 1000.0)
Set one of these parameters to enable
L3-25
:
•
L3-04 = 2 [Stall Prevention during Decel = Intelligent (Ignore Decel Ramp)]
•
L3-11 = 1 [Overvoltage Suppression Select= Enabled]
Note:
If you set this value incorrectly when
L3-11 = 1
, it can cause large current ripples and
ov [Overvoltage]
,
Uv1 [DC Bus Undervoltage]
, or
oC
[Overcurrent]
faults.
Manually Adjust Parameters
Use this formula to find the load inertia ratio:
