Parallel and double–cam arrangement of linear motors
Note
Only identical linear motors (the same forces, winding types,
secondary section types and air gap) may be connected in parallel.
(Order designation or Order No. [[MLFB] of the primary sections to be
connected in parallel must be identical up to the winding sense and/or
primary section length.)
If linear motors in an axis are connected in parallel, the position of the
primary sections with respect to one another and to the secondary
sections must exhibit a specific grid, in order to achieve a matching
electrical phase position.

Linear Motors
The temperature sensors can be evaluated, for example, as follows:
Temperature sensor
– Motor 1:
Evaluated by the drive
– Motor 2:
Not connected
(short–circuited and connected with PE)
Temperature switch
– Motor 1 and 2: Evaluated by a PLC
