Inserting and routing the cables

6.2.1

Connecting the machine for a specific direction of rotation

The technical data stipulate the following with respect to the motor connection:
● Direction of rotation
● The number and arrangement of the terminal boxes
● The circuit and connection of the motor winding
Direction of rotation
If the machine has one shaft extension or two shaft extensions with different diameters, the
direction of rotation when looking at the front of the single or the thicker shaft extension is
defined as follows:
● If you connect line cables with a phase sequence of L1, L2, L3 at U, V, W, the resulting
● If you interchange two connections, e.g. you connect L1, L2, L3 to V, U, W, the resulting
Changing the direction of rotation
If you want to operate the machine in the opposite direction to the direction stated in the order,
please consult your contact partner at Siemens.
Directions of rotation, which may be required for an application in a particular plant or system,
are not shown on the rating plate. Please take these requirements into consideration when
connecting up the machine.

Direction of rotation of the motor when looking at DE
Machines that must run only in one specific direction of rotation are marked as follows.
– On the rating plate with a direction of rotation arrow
– With terminal designations in the required phase sequence
The machine can malfunction or be damaged if it is operated other than how it was originally
ordered or with the incorrect direction of rotation.
