Maximum Number of Absolute Encoder Rotations
Set the maximum number of absolute encoder rotations.
Set fixed parameter No. 38 (Maximum Number of Absolute Encoder Rotations) to the same
value as the Pn205 SERVOPACK parameter.
Set fixed parameter No. 38 and SERVOPACK parameter Pn205 to the same values to ensure
that correct motion control is performed and to prevent position variation.
Multiturn limit setting mismatch detection can be used to determine whether both values match.
Important
Refer to the following section for details.

Setting the Origin
OL
48 (Zero Point Position Offset in Machine Coordinate System) is always valid when
the axis type is set to a finite-length axis. Do not change the setting of OL
machine is operating.
There is a risk of machine damage or an accident.
Set the origin after you reset the absolute encoder to set the origin of the machine coordinate
system and to create the machine coordinate system. Use the following procedure to do so.
Perform this procedure only once when the machine is initially started. This procedure is not
necessary at any other time.
START
Servo ON
Jog to near the origin.
Move to the origin in STEP Mode.
Set OL
48 to the value of
(OL
48 − IL

Set the origin with the ZSET command.
