10 Absolute Position Detection
10.2.2 Setting Related Parameters
10-6
(b) Axis Selection
• MP2100/MP2100M fixed parameter 1, bit 0
This setting is used to set either an infinite or finite length axis for controlled axis movement.
Refer to 10.3 Using an Absolute Encoder for position management methods for finite and infinite length
axes.
(c) Infinite Length Axis Reset Position
• MP2100/MP2100M fixed parameter 10
The Infinite Length Axis Reset Position is used to set the reset position of infinite length axis per rotation in
reference units. This parameter is enabled when an axis type is set to a infinite length axis.
(d) Maximum Number of Absolute Encoder Turns/Multiturn Limit Setting
• MP2100/MP2100M fixed parameter 38
•
Σ
-
II
and Σ-
III Series SERVOPACK parameter Pn20
5
These parameters determine the maximum value of the number of encoder turns managed by the
SERVOPACK and MP2100/MP2100M. The setting is determined by the SERVOPACK that is used and the
type of axis, as shown in the following table.
* A fixed parameter setting error will occur if fixed parameter 38 is set to
65535 for the
Σ
-
ΙΙ
Series with an infinite length axis.
If the above settings are not used, the position may be offset. Set the parameters carefully.
