The motor and the load has been connected.
The inertia identification process is as below.
Set Fn69
to 3
Set PA53
to 1
Check the
Dp20-Jr Value
Input this value
into PA29
Set Fn69
to 0
E-SET
save and
restart
Set PA53
to 0
If external enable
function is used,
this step can be
skipped.

ATTENTION
After the inertia identification is completed, please be sure to set Fn69 to
0, otherwise normal servo operation will be affected.
After the inertia recognition, the drive can recognize the field condition
better. However, the gain parameters cannot be generated automatically,
so the rigidity class (PA33) or gain parameters such as PA5 and PA6
need to be set.
The dP-20Jr value is generally set to be about 300. If the value is too
large, such as over 1000, or is negative (with a decimal point below each
number), it indicates that the driver has failed to correctly identify the
inertia. In the case of uneven load in general conditions (such as gear
drive, belt drive, etc.), the inertia may not be recognized by the drive.
If the inertia recognition is not completed, it will not affect the normal use
of the drive.
