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 axes

(which are not path axes) and from their associated coupling factors.

● Velocity components from other leading axes and overlaid motions of the following axis are

not taken into account.

End of part program

1) No coupling is active after Power On.

Block search

A search during active coupling (EG) is possible under the following supplementary conditions:

● Simulation is exclusively with setpoint coupling.

● No cross-channel leading axes may be disabled.

● Axis movements for which all real positions are known to the NC.

If it is technically not sensible or not possible to permit the target block for a block search with

calculation or SERUPRO within a part program section with active coupling, this section can

be locked for "continue machining at the contour".

● IPTRLOCK()

● IPTRUNLOCK()
