5.10 Converter operation
Immunity to interference
The machines fulfill the requirements of interference immunity in conformity with EN /
IEC 61000-6-2. For machines with integrated sensors, e.g. PTC thermistors, the operating
company must ensure sufficient interference immunity by selecting a suitable sensor signal
cable (possibly with shielding, connected in the same way as the machine feeder cable) and a
suitable evaluation unit.
When operating the machines from a converter at speeds higher than the rated speed, carefully
comply with the mechanical speed limits (safe operating speed EN / IEC 60034-1).

Converter operation
1FU9 motors are operated on the converter in the SYNCHRONOUS U/f operating mode.
5.10.1
Parameterizing the converter
• If the design of the motor requires connection to a particular converter type, the rating plate
will contain corresponding additional information.
• Correctly parameterize the converter. Parameterizing data can be taken from the machine
rating plates.
You can also find parameter data here:
– Operating instructions for the converter.
– SINAMICS Configuration Manuals.
• Do not exceed the specified limit rotational speed n
plate n
• Check that the machine is cooled sufficiently for commissioning purposes.
5.10.2
Converter input voltage
The insulation system of SIMOTICS machines complies with the requirements of stress category
C (IVIC C = high stress). If voltage peaks higher than those specified according to IVIC C can occur,
contact the Service Center.
• For a line supply voltage (converter input voltage) up to max. 480 V, and when controlled
from a SINAMICS converter with uncontrolled/controlled infeed: Comply with the guidelines
for configuring motor and converter.
• The insulation system of the machines is not suitable for a line voltage (converter input
voltage) greater than 480 V.
• Operation with a converter from another manufacturer: Comply with the permissible voltage
peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the
particular line voltage (converter input voltage) and the motor insulation system.
