4.14 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).

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 converter operating instructions
– In the TIA selection tool
– In the SINAMICS Configuration Manuals
– For explosion-proof machines, also in the declaration of compliance with the order 2.1.
• Do not exceed the specified maximum speed limit n
rating plate n
speed.
• Carefully check whether it is guaranteed that the machine is cooled for commissioning.
4.14.2

Converter input voltage

The insulation system of SIMOTICS LV machines always 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 G/SINAMICS S converter with uncontrolled/controlled infeed: Comply
with the guidelines for configuring motor and converter.
• For line voltages (converter input voltages) higher than 480 V, motors, which are ordered
for converter operation, have an appropriate insulation system.
• 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.
