Fieldbus control
147
The fieldbus control interface
The communication between a fieldbus system and the drive employs data sets.
One data set (abbreviated DS) consists of three 16-bit words called data words
(DW). The Winder Program supports the use of six data sets, three in each direction.
Table 2 Default connections for the cyclical fieldbus communication.
* The index number is required when data word allocation to process data is defined via the fieldbus
parameters at group 51. The function is dependent on the type of the fieldbus adapter
** This draw is not controlled by Group 61; it is always added to the speed reference.
Note: These scaling values are only applicable when Par. 90.0x is left at 0.
