Abstract

A drive system includes a central module, distributors, and drives. Each drive is assigned a respective distributor. A first hybrid cable is led from the respective drive through a respective first cable gland of the respective distributor into the respective distributor, a second hybrid cable is led from the central module through a second cable gland into a first distributor, and a further second hybrid cable is led from a respective distributor through a further second cable gland into a respective distributor arranged downstream. A respective first data cable is led from the respective drive through a respective third cable gland into the respective distributor, and a respective second data cable is led from the respective drive through a respective third cable gland into the respective distributor.

First claim

The invention claimed is:

1 . A drive system, comprising:
a central module; a plurality of distributors; and a plurality drives, each drive corresponding to a respective distributor; wherein each drive is connected to the respective distributor by a first hybrid cable that extends from the drive through a first cable gland of the respective distributor into the respective distributor and by a first data cable and by a second data cable that extend from the drive through a respective third cable gland of the respective distributor into the respective distributor; wherein a first second hybrid cable extends from the central module through a first second cable gland of a first one of the distributors into the first one of the distributors; and wherein a second second hybrid cable extends from a second second cable gland of the first one of the distributors through a first second cable gland of a downstream one of the distributors into the downstream one of the distributors.

2 . The drive system according to claim 1 , wherein the distributors are arranged in a line and/or in a series.

3 . The drive system according to claim 1 , wherein the distributor includes a lower part having an eyelet.

4 . The drive system according to claim 3 , wherein a clear inside diameter of the eyelet decreases and/or monotonously decreases with increasing distance from the first cable gland.

5 . The drive system according to claim 4 , the clear inside diameter is measured perpendicular to a straight line connecting the eyelet and the first cable gland.

6 . The drive system according to claim 3 , wherein the lower part includes U-shaped foot parts having legs adapted to accommodate first bolts therethrough, and the eyelet is adapted to receive a second bolt therethrough to fasten to a wall.

7 . The drive system according to claim 6 , wherein the eyelet has a clear inside diameter that decreases with increasing distance from the foot parts.

8 . The drive system according to claim 6 , wherein the eyelet has a clear inside diameter that decreases with increasing distance from the foot parts measured transversely to a connecting line between the eyelet and a center of gravity of the foot parts.

9 . The drive system according to claim 1 , wherein the central module is arranged in a switch cabinet.

10 . The drive system according to claim 1 , wherein the central module includes a low-voltage connection, an extra-low-voltage connection, and a controller connected to the drives and adapted for data exchange.

11 . The drive system according to claim 10 , wherein the low-voltage connection is adapted to connect to a three-phase voltage network, and the extra-low voltage connection is adapted to supply 24-volt power supply.

12 . The drive system according to claim 1 , wherein the first hybrid cable includes low-voltage lines and extra-low-voltage lines.

13 . The drive system according to claim 12 , wherein the low-voltage lines include neutral conductors.

14 . The drive system according to claim 1 , wherein the second hybrid cable includes low-voltage lines, extra-low-voltage lines, and a data line.

15 . The drive system according to claim 14 , wherein the low-voltage lines include neutral conductors.

16 . The drive system according to claim 14 , wherein the data line of the first second hybrid cable is arranged through the second data cable and/or is electrically connected to a data line of the second data cable, and the data line of the second second hybrid cable is arranged through the second data cable and/or is electrically connected to the data line of the second data cable.

17 . The drive system according to claim 1 , wherein the distributor has a lower part and an upper part arranged on the lower part, and all cable glands are arranged on the lower part.

18 . The drive system according to claim 17 , wherein the lower part includes a switch adapted to be actuated from outside and/or from an outer environment of the lower part, the switch adapted to disconnect and/or electrically disconnect low-voltage lines of the first hybrid cable.

19 . The drive system according to claim 17 , wherein the lower part is box-shaped.

20 . The drive system according to claim 17 , wherein the lower part includes a bottom wall, a front wall adjacent to the bottom wall, a first side wall adjacent to the bottom wall and to the front wall, and a second side wall adjacent to the bottom wall and to the front wall and arranged at a distance from the first side wall.

21 . The drive system according to claim 20 , wherein the second side wall is aligned parallel to the first side wall and/or arranged opposite the first side wall on the lower part.

22 . The drive system according to claim 20 , wherein the first cable gland is arranged in the front wall, the third cable gland is arranged in the front wall, the second cable gland is arranged in the second side wall, and/or a switch adapted to disconnect low-voltage lines of the first hybrid cable is arranged in the first side wall.

23 . The drive system according to claim 17 , wherein the upper part has a flat surface section arranged as a labeling surface and having a smaller distance to the first, second and/or third cable gland than to an eyelet of the lower part.

24 . The drive system according to claim 17 , wherein further cable glands and/or unused cable glands are arranged on the lower part and/or on a front wall and a second side wall of the lower part.
