Set the parameters correctly as shown in the above table. Otherwise, correct motion control will not be per-
formed resulting in position error.

* This value depends on the setting of Pn212 (PG dividing ratio). The values in the table are
the maximum values.
These parameters determine the maximum value of the number of encoder turns managed by the
SERVOPACK and MP2300.
For an infinite length axis, set the parameters as shown in the table below.

* If the MP2300 fixed parameter 38 is set to 65535 when using a Σ-II series SERVOPACK for an
infinite axis, a fixed parameter setting error will occur.
