Determination of the mass moment of inertia
The mass moment of inertia of the total system must be known (i.e. motor + rigidly
coupled load) both for the automatic calculation of the speed controller parameters
and for the precontrol of the acceleration torque.
The mass moment of inertia can be determined by an acceleration test if it is un-
known.
Therefore the system must be accelerated with defined, constant torque. It must be
ensured that there is no significant, acceleration-independent load torque by the
application.
The following formula is valid:
Example:
the following acceleration was recorded with COMBIVIS:
