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.
PROFIdrive drive - Encoder on the technology module (TM)
Data exchange with the drive
In this area, you can configure the data exchange with the drive.
● Drive message frame:
setting in the device configuration.
● Reference speed:
In this field, configure the reference speed of the drive in accordance with the
manufacturer's specifications. The specification of the drive's speed occurs as a
percentage of the reference speed in the range from -200% to 200%.
● Maximum speed
● Invert drive direction
Select the check box if the rotation direction of the drive should be inverted.

In the drop-down list, select the frame for the drive. The specification must match the
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).
