NOTICE
Emitted interference when operated with frequency converter
If operated with a frequency converter, the emitted interference varies in strength,
depending on the converter design. You must observe the EMC information from the
manufacturer of the converter. In this way, you will avoid exceeding the limit values
stipulated by EN 50081 for the drive system, which consists of a motor and converter.
NOTICE
No guarantee the motor will function with other converters
1FW4-motors have been designed and tested as a system using SINAMICS-converters.
SINAMICS converters work with control software that has been specially developed for the
1FW4-motors. If other converters are used, there is no guarantee that the motor will
function correctly and there is no liability for consequential damage to the motor.
The motor generally satisfies the requirements for interference immunity as per EN 50082.
[ID 837.01]
1.4 Magnetic fields of 1FW4 motors
Safety information
For 1FW4-series motors in the assembled state, the field of the permanent magnets is
channeled through the iron circuit of the motor. As a result, no harmful magnetic field can be
detected outside of the motor in accordance with EN 50061.
WARNING
Danger posed by magnetic fields when motor is open
The permanent magnet rotor may only be removed by the manufacturer and the bearing
may only be replaced by certified service partners. Should on-site removal of the magnetic
rotor or a bearing change prove necessary, please contact the Siemens Service Center.
WARNING
Effect of strong magnetic fields on personnel
Strong magnetic fields can directly affect persons and cause damage. The handling of
components containing permanent magnets is strictly prohibited for all persons with
pacemakers, metallic implants, and foreign objects that conduct electricity or magnetism. A
medical report is required for any exceptions to this ruling. Unambiguous access rules must
be established in accordance with the magnetic fields prevailing in the workplace. Clearly
mark the boundaries of the areas where standing is permitted.
