Siemens SIMOTICS L-1FN3 - Inspection and Maintenance

9.2 Inspection and maintenance
Performing maintenance work on the motor
Note
It is essential that you observe the safety information provided in this documentation.
As a result of their inherent principle of operation, linear motors are always wear-free.
To ensure that the motor functions properly and remains free of wear, the following
maintenance work needs to be carried out:
• Regularly check that the traversing paths are free
• Regularly clean the motor space and remove foreign bodies (e.g. chips)
• Regularly check the condition of the motor components.
• Check the current consumption in the de󹪝ned test cycle (compare with values of the
reference travel)
Intervals between maintenance
Since operating conditions di󹪜er greatly, it is not possible to specify intervals between
maintenance work.
Indications that maintenance work is required
• Dirt in the motor cabinet
• Distinctive changes in the behavior of the machine
• Unusual sounds emitted by the machine
• Problems with positioning accuracy
• Higher current consumption
