PCU Data Settings for Using Absolute Encoders
The parameters and data required when using absolute encoders are as fol-
lows:
Axis Parameter Area
The following parameters are for the operation mode for origin searches.
d = 1860 hex + (Axis No.

×
14 hex
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
in the Servo Parameters match.
If the settings do not match, reading absolute data will not be possible, or
another malfunction may occur.
