Parameters for Using G-series Absolute Encoders
Parameters for Using W-series Absolute Encoders
When using a Servomotor with absolute encoder, select whether the absolute
encoder will be used as an absolute encoder or as an incremental encoder.
These parameter settings are disabled if a Servomotor with incremental
encoder is used.
Set this parameter to 1 or 2 for a G-series Servo Drive, and 1 for a W-series
Servo Drive, if using a Servomotor with absolute encoder as a Servomotor
with incremental encoder.
When using an absolute encoder, make sure that the settings for the encoder
type in the Axis Parameters and
Operation Switch when Using Absolute
Encoder (Pn00B for G Series and Pn002.2 for W Series) in the Servo Param-
eters match.
A motor with an absolute encoder cannot be used with a SMARTSTEP Junior
Servo Drive. When using a SMARTSTEP Junior Servo Drive, Pn002.2 is not
supported. Use the Servo Drive as for an incremental encoder.
If the settings do not agree, origin searches may not be possible and other
malfunctions may occur.
