6.7 Configuring the External Encoder technology object
Encoder type
Steps per revolution:
Number of revolutions:
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
Bits for the multiplication factor of the absolute
value of the fine resolution (Gn_XIST2)
Encoder type
Distance between two increments:
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
Encoder type
Distance between two increments:
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
Bits for the multiplication factor of the absolute
value of the fine resolution (Gn_XIST2)
Invert encoder direction
Select this check box if you would like to invert the actual value of the encoder.

Rotary cyclic absolute
In this field, configure the number of steps that
the encoder resolves per revolution.
In this field, configure the number of revolutions
that the absolute value encoder can detect.
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
In this field, configure the number of reserved bits
for the multiplication factor of the absolute value
of the fine resolution (Gn_XIST2).
Linear incremental
In this field, you can configure the distance be-
tween two steps of the encoder.
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
Linear absolute
In this field, you can configure the distance be-
tween two steps of the encoder.
