After this dialog has been confirmed using the button: “OK”, the dialog: “DP
Slave properties” opened.
Depending on the drive functionality to be used, you must select the correct
message frame type from the listbox: default. The selected message frame type
only defines the number of cyclically transferred process data units within the
cyclic message frames.
The number of cyclically transferred process data units depends on:
– The number of axes per drive module
– The number of encoders used per axis
– The drive functionality used.
The following message frame types are predefined for parameterization of the
DP slave 611U:
