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
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 motions of the following axis
are not taken into account.

Response to POWER ON, RESET, operating mode change, block search

No coupling is active after POWER ON.
The status of active couplings is not affected by RESET or operating mode switchover.
More detailed information on special states can be found under "Performance Overview of the
Electronic Gearbox".
Block search for certain simulations
Certain active axis couplings can be simulated in the block search. As this does not apply to
all possible coupling types, it is also possible to skip areas in which block searches cannot be
made with an "automatic interrupt pointer". The electronic gear can be simulated for all block
search types under the following conditions:
• Simulation always takes place with setpoint coupling.
• No cross-channel leading axes may be disabled.
• Axis movements for which all real positions are known to the NC.
