Deleting The Definition Of An Electronic Gear (Egdel); Rotational Feedrate (G95) / Electronic Gear (Fpr) - Siemens SINUMERIK 840D sl Programming Manual

Work preparation
3.16 Axis couplings
Variant 2:
Syntax
EGOFS(following axis,leading axis1,
...,leading axis5)
At least one leading axis must be specified. 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.
Variant 3:
Syntax
EGOFC(following
spindle1)
Note
This variant is only permitted for spindles.
3.16.4.4

Deleting the definition of an electronic gear (EGDEL)

An EG axis group must be switched-out before its definition can be deleted.

3.16.4.5

Rotational feedrate (G95) / electronic gear (FPR)

The FPR command can be used to specify the following axis of an electronic gear as the axis,
which determines the revolutional 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.
● Speed parts of linear or non-modulo leading axes and overlaid movement of the following
axis are not taken into account.

Meaning
The electronic gear is deactivated. The following spindle continues
to traverse at the speed/velocity that applied at the instant of deac‐
tivation. This call triggers a preprocessing stop.
Meaning
The coupling definition of the axis group 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.
Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Meaning
This command parameter setting made it
possible to selectively remove the influence
of the individual leading axes on the following
axis' motion.
