* The actual value depends on the value of Pn212 (PG Dividing Pulse). The values shown here are the max. val-
ues that can be set.
 If the above settings are not used, correct motion control will not be performed. Set the parameters carefully.
( 4 ) Maximum Number of Absolute Encoder Turns Rotation/Multiturn Limit Setting
These parameters determine the maximum value of the number of encoder turns managed by the SERVOPACK and
Machine Controller.
The setting is determined by the SERVOPACK that is used and the type of axis (Machine Controller fixed parameter 1,
bit 0). Set the parameters as shown in the following table when using an axis as a finite length axis.
