Configuring
6.6 Configuring the positioning axis/synchronous axis technology object
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.
Analog driver connection - PROFIdrive encoder on PROFINET/PROFIBUS
Data exchange with the drive
In this area, you can configure the data exchange with the drive.
● Drive message frame:
● Reference speed:
The reference speed of the drive is the speed, with which the drive spins when there is an
output of 100% at the analog output. The reference speed must be configured in the
drive, and transferred into the configuration of the technology object.
The analog value that is output at 100% depends on the type of the analog output. As an
example, with an analog output with +/- 10 V, the value 10 V is output at 100%.
Analog outputs can be overloaded by about 17%. This means that an analog output can
be operated in the range from -117% to 117%, insofar as the drive permits this.
● Maximum speed
● Invert drive direction
Select the check box if the rotation direction of the drive should be inverted.

Since the analog drive is controlled via an analog signal, the selection of the frame type is
omitted.
In this field, specify the maximum speed of the drive.
Linear incremental
In this field, you can configure the distance
between 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
between 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 the multiplication factor of the absolute value
of the fine resolution (Gn_XIST2).
