4.1.15.3 Electronic gearbox (Gearing)
The motion function ”Gearing” (electronic gearbox) moves Compax3 synchronously
with a leading axis.
A 1:1 synchronity or any transmission ratio can be selected via the gear factor.
A negative sign – which means reversal of direction – is permitted.
Function Electronic gearbox (Gearing)
The position of a master axis can be detected via:
+/-10V analog input
Step / direction input (X11/6, 7, 8, 12)
the encoder input (X11/6, 7, 8, 12) or
HEDA, if Compax3 is used as master drive.
The master signal detection is configured under synchronization.
Settings of the ”Gearing” motion function
Transmission ratio slave / master
The transmission ratio (gear factor) can be entered in ”Gearing numerator” (at
”Gearing denominator” = 1).
You will obtain an exact image of a non-integral transmission ratio by entering the
value integrally as a fraction with numerator and denominator. This helps to avoid
long-term drifts

nator
Here you can define the acceleration for the drive to reach the desired synchronity.
You can switch dynamically between 2 gearing motion sets with different gear fac-
tors.
The set acceleration counts as deceleration if the gear factor is reduced.
Dynamic switching between the gearing motion function and positioning functions
(MoveAbs, MoveRel, RegSearch) is possible.
