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

M3: Coupled axes
5.4 Electronic gearbox (EG)
Block change behavior
In the EG activation commands (EGON, EGONSYN, EGONSYNE), it can be specified for
which condition (with respect to synchronism) the next block of the parts program is to be
processed. Options:
• NOC: no conditions
• FINE: Sum of the difference between the setpoint and actual positions of all axes less than
machine data:
MD37210 $MA_COUPLE_POS_TOL_FINE
• COARSE: Sum of the difference between the setpoint and actual positions of all axes less
than machine data:
MD37200 $MA_COUPLE_POS_TOL_COARSE
• IPOSTOP: When the specified end positions of the axes is reached

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).
