Note
Converter
• If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures,
manufacturer).
• Avoid that the specified limit values stipulated for the drive system (consisting of the
motor and converter) are exceeded.
• You must observe the EMC information from the manufacturer of the converter.
• The most effective method of shielding is to conductively connect a shielded machine
supply cable to the metal terminal box of the machine (with a metal screw connection)
over a large surface area.
• On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages
caused by the converter may occur on the sensor cable.
When used in accordance with their intended purpose, and operated on a line supply with
characteristics according to EN 50160, the enclosed machines comply with the requirements
of the EC Directive regarding electromagnetic compatibility.
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).

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 find parameter data here:
– In the operating instructions for the converter.
– In the SIZER engineering tool
– In the SINAMICS Configuration Manuals.
– For explosion-protected machines, also in the declaration of compliance with the order
