Data exchange with encoder
In this area, you can configure how the encoder data are to be evaluated. The specifications
must match those in the device configuration.

6.6 Configuring the positioning axis/synchronous axis technology object
The encoder data is transmitted with the drive frame. Therefore, no frame selection is
available.
Depending on the selected encoder type, configure the following parameters:
Rotary incremental
In this field, configure the number of steps that
the encoder resolves per revolution.
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
Rotary 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 reserved 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).
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).
