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 specied 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 eective 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 proper and intended purpose and operated on an electrical
supply system 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 fulll the requirements of interference immunity in conformity with EN /
IEC61000-6-2. For machines with integrated sensors, e.g. PTC thermistors, the operating
company must ensure sucient 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/IEC60034-1).
4.14 Converter operation
4.14.1 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 nd parameter data here:
– In the converter operating instructions
– In the TIA selection tool
– In the SINAMICS Conguration Manual if available
– For explosion-proof machines, also in the declaration of compliance with the order 2.1.
