Variant 3
EGOFC(following spindle)
The electronic gear is deactivated. The following spindle continues to traverse at the
speed/velocity that applied at the instant of deactivation. This call triggers a preprocessing
stop.
Note
Call for following spindles available. For EGOFC a spindle identifier must be programmed.
2.4.5 Deleting an EG axis group
An EG axis grouping must be switched off, as described in Chapter "Switching off a EG Axis
Group", before its definition can be deleted.
EGDEL(following axis)
The defined coupling of the axis grouping is deleted. Additional axis groups can be defined
by means of EGDEF until the maximum number of simultaneously activated axis groups is
reached.
This call triggers a preprocessing stop.
2.4.6 Interaction between rotation feedrate (G95) and electronic gearbox
The FPR( ) part program command can be used to specify the following axis of an electronic
gear as the axis, which determines the rotational feedrate. The following behavior is
applicable in this case:
• The feedrate is determined by the setpoint velocity of the following axis of the electronic
• The setpoint velocity is calculated from the speeds of the leading spindles and modulo
• Velocity components from other leading axes and overlaid motions of the following axis
