Configuration - Data exchange
Configuration - Data exchange
In the "Data transmission" configuration window, configure the data transmission to the
encoder. The configuration varies according to the encoder coupling:
●
Encoder to technology module (Page 149)
●
Encoder to PROFINET/PROFIBUS (Page 151)
Encoder to technology module
Data exchange with encoder
In this area, you can configure the encoder frame and the criteria for how the encoder data
are to be evaluated. The specifications must match those in the device configuration.
Encoder message frame
In the drop-down list for the technology module, select the message frame that you have
configured in the technology module.
Encoder type
In this area, you can configure how the encoder data are to be evaluated. The specifications
must match those in the device configuration.
Encoder type
Rotary incremental
Steps per revolution:
In this field, configure the number of steps that
the encoder resolves per revolution.
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
Encoder type
Rotary absolute
Steps per revolution:
In this field, configure the number of steps that
the encoder resolves per revolution.
Number of revolutions:
In this field, configure the number of revolutions
that the absolute value encoder can detect.
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
In this field, configure the number of reserved bits
for fine resolution within the incremental actual
value (Gn_XIST1).
Bits for the multiplication factor of the absolute
value of the fine resolution (Gn_XIST2)
In this field, configure the number of reserved bits
for the multiplication factor of the absolute value
of the fine resolution (Gn_XIST2).
