Performance Overview Of Eg (Summary) - Siemens SINUMERIK 840D sl Function Manual

Block change mode
1. When an EG axis group is activated, it is possible to specify the conditions under which a
part program block change is to be executed:
2. The specification is made with a string parameter with the following meaning:
3. "NOC": Immediate block change
4. "FINE": Block change if "Fine synchronism" is present
5. "COARSE": Block change if "Coarse synchronism" is present
6. "IPOSTOP": Block change if "Setpoint synchronism" is present
Note
When programmed in activation calls EGON, EGONSYN, EGONSYNE, each of the
above strings can be abbreviated to the first two characters.
If no block change has been defined for the EG axis group and none is currently specified,
"FINE" applies.

Performance Overview of EG (Summary)

EG
An EG has:
• a maximum of 5 lead axes
• 1 Following axis
• a maximum of 5 assigned curve tables or
• a maximum of 5 assigned coupling factors (Z/N) or
• a combination of curve tables and coupling factors for a maximum of 5 leading axes
Following axis
A following axis can:
• identify the EG uniquely
• be the leading axis of a different EG (cascading)
• not simultaneously be the leading axis of the same EG (no feedback)
• not be command axis
