External moment of inertia / load
The external moment of inertia is required for adjusting the servo controller. The
more accurately the moment of inertia of the system is known, the better is the
stability and the shorter is the settle-down time of the control loop.
It is important to specify the minimum and maximum moment of inertia for best
possible behavior under varying load.
If you do not know the moment of inertia, klick on "Unknown: using default values".
You have then the possibility to determine the moment of inertia by means of
automatic load identification (see page 190).
Minimum moment of inertia / minimum load
Maximum moment of inertia / maximum load
Enter minimum = maximum moment of inertia when the load does not vary.
The reference system for positioning is defined by:
a unit,
the travel distance per motor revolution,
a machine zero point with true zero,
positive and negative end limits.
