Set the number of feedback pulses per motor rotation.
Set the value after multiplication to match the specifications of the motor to be used. For example, if a 16-bit encoder is
used, set 2

65534
Set the maximum number of rotations for the absolute encoder when an absolute encoder is used.
Set it according to the setting of the encoder to be used.
•
Σ
Series: Always set to 99999.
•
Σ
-II or
Σ
-III Series: Set to the same value as the multiturn limit in the SERVOPACK.
For axes set as infinite axes (Function Selection 1 (fixed parameter 1), bit 0 set to 1), set to 65534 max. (same value as
Pn205).
This parameter is used to manage position data when an absolute encoder is used and an infinite length axis has been set.
