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 fine resolution in the absolute actual value
(GN_XIST2)
Invert encoder direction
Select this check box if you would like to invert the actual value of the encoder.

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.
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 fine resolution within the absolute actual value
(GN_XIST2).
