 The travel distance is the distance for one operation in the forward or reverse direction.
During multiple operations, the operation starting position may move in one direction or the
other. Confirm the possible operating range for each measurement or operation.
 Depending on the parameter settings and the moment of inertia of the machine, overshoot-
ing and undershooting may occur and may cause the maximum speed setting to be
exceeded temporarily. Allow sufficient leeway in the settings.
When Measurement Is Not Correct
Estimating the moment of inertia ratio cannot be performed correctly if the torque limit is
activated. Adjust the limits or reduce the acceleration rate in the reference selection so
that the torque limit is not activated.
