Motor inertia automatic measurement parameters
Inertia automatic measurement function is only for IM motor PG vector control (00-21(P.300)=4) or PM motor PG
vector control (00-21(P.300)=5).
When performing inertia automatic measurement function, set 05-00(P.301)=10, press
FWD
or
REV
on keypad,
the inverter will automatically calculate the following parameters: 05-18(P.319)。
The steps of automatic measurement of inertia are as follows:
start
00-21(P.300)=4
05-00(P.301)=10
Determine motor

Press the forward/Reverse
key to start measuring
