Absolute Encoder Origin Section 8-6
Parameters for Using W-series Absolute Encoders
When using a Servomotor with an absolute encoder, select whether the abso-
lute encoder will be used as an absolute encoder or as an incremental
encoder. Set this parameter to 0 if using the absolute encoder as an absolute
encoder.
When using W-series Servo Drives, the parameter size is the value to be
specified when transferring the Servo Parameter including Pn002.
G-series Origin Position Offset Parameters
W-series Origin Position Offset Parameters
This parameter sets the offset for the mechanical origin from the absolute
encoder's absolute value data. The present position will be the absolute value
data that was read added to the value in this parameter, and that position is
set as the origin.
Note When using the zero point position offset setting function with Position Control
Units with unit version 2.0 or later, Pn808 is automatically overwritten when an
origin search is performed with an absolute encoder. (Refer to
8-6-5 Absolute
Encoder's Origin (Zero Point) Position Offset Setting ) To achieve this, the
Position Control Unit reads and writes Servo Parameter for Pn808 when the
origin search operation is started and when it is completed.
