Deleting An Eg Axis Group; Interaction Between Rotation Feedrate (G95) And Electronic Gearbox - Siemens SINUMERIK 840D Function Manual

The influence of the specified leading axes on the slave is selectively inhibited. This call triggers
a preprocessing stop.
If the call still includes active leading axes, then the slave continues to operate under their
influence. If the influence of all leading axes is excluded by this method, then the following axis
is braked to a standstill.
If the command EGONSYN is deactivated selectively, no axis movement is performed.
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 name must be programmed.
14.4.6

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.
14.4.7

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. Please note the following with
respect to this command:
● The feedrate is determined by the setpoint velocity of the following axis of the electronic
gear.
● The setpoint velocity is calculated from the speeds of the leading spindles and modulo axes
(which are not path axes) and from their associated coupling factors.
● Velocity components from other leading axes and overlaid motion of the following axis are
not taken into account.
