Coupled Motors; Operating Motors Connected To An Axis In Parallel - Siemens SIMOTICS L-1FN3 Configuration Manual

Coupled motors

10.1

Operating motors connected to an axis in parallel

If the motor force of a single motor is not sufficient for the drive application, you can
distribute the required motor torque over two or more motors.
Mount the motors on the same slide of an axis. The motors are then mechanically coupled.
You have two options for supplying the individual motors:
● Each motor is operated on its own Motor Module with its own encoder. This operation
does not represent an electrical parallel connection. The motors only operate together
mechanically. This version is not discussed in this manual.
● All of the motors are connected to the same Motor Modules. In this case, the article
numbers of all of the motors involved must be the same. The motors are then electrically
connected in parallel, and operate in the parallel mode.
If you have any questions in this regard, then contact your local Siemens office. For
example, you can obtain information about optimally engineering or dimensioning drive
systems with linear motors operating in parallel.
Note
Country-specific safety requirements for parallel operation
Country-specific safety requirements and regulations apply when connecting motors in
parallel at a Motor Module.
For example, in the US, for special motor protection, carefully comply with the requirements
laid down in standards NFPA 70 and NFPA 79.
