* 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.
( 3 ) 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.
For an infinite length axis, set the parameters as shown in the table below.

* If the Machine Controller fixed parameter 38 is set to 65535 when using a
for an infinite axis, a fixed parameter setting error will occur.
 If the above settings are not used, correct motion control will not be performed resulting in position error. Set
the parameters correctly.
