Gantry arrangement
If different load conditions occur during operation, both locally and temporally,
and a sufficient rigidity between the motors cannot be ensured, the operation
should be planned with two linear scales and drive controllers (Gantry ar‐
rangement). This is frequently the case with axis in a Gantry structure, for ex‐
ample.
Within a Gantry arrangement, even parallel connected motors can
be used.
Double comb arrangement (Gantry)
Within a Gantry arrangement, the primary parts in feed direction can be me‐
chanically coupled and arranged in the form of a double comb arrangement.
① Control unit
② Controller (2 pcs.)
③ Length measuring system (2 pcs.)
Fig. 9-26: Gantry arrangement (double comb)
With Gantry arrangements it must be remembered that the motors may be
stressed asymmetrically, although the position offset is minimized. As a con‐
sequence, this permanently existing base load may lead to a generally higher
stress than a single arrangement. This must be taken into account when the
drive is selected.
