Definition Of An Eg Axis Group - Siemens SINUMERIK 840D Function Manual

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.

Definition of an EG axis group

Note
The following definition commands and switch instructions of the electronic gearbox must all be
contained in only one block of a parts program.
All commands of the electronic gearbox result in a preprocessing stop, except for the activation
commands:
● EGON
● EGONSYN
● EGONSYNE
Definition and activation
The definition described below and activation are separate processes. An activation is not
possible unless it has been defined previously.
Definition of an EG axis group
An EG axis group is defined through the input of the following axis and at least one, but not more
than five, leading axis, each with the relevant coupling type:
EGDEF(following axis, leading axis1, coupling type1, leading axis2, coupling type 2,...)
The coupling type does not need to be the same for all leading axes and must be programmed
separately for each individual leading axis.
Coupling type:
Evaluate actual value of leading axis: 0
Evaluate setpoint of leading axis: 1
The coupling factors are preset to zero when the EG axis group is defined. As such, the group
has no effect on the following axis until it is activated. (See EGON, EGONSYN, EGONSYNE).
Preconditions for defining an EG axis group:
No existing axis coupling may already be defined for the following axis. (If necessary, an
existing axis must be deleted with EGDEL.)
EGDEF triggers preprocessing stop with alarm.
