Siemens SIMOTICS SD User Manual

Immunity to interference
The machines ful󹪝ll 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 su󹪟cient 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).
4.13 Converter operation
4.13.1 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 Con󹪝guration Manual if available
– For explosion-proof machines, also in the declaration of compliance with the order 2.1.
• Do not exceed or fall below limit speed n
min
or n
max
. If no other value is speci󹪝ed, the minimum
speed limit is n
min
5Hz. The speed limits are either stamped on the rating plate or the
supplementary plate for converter operation as the highest or lowest speci󹪝ed speed.
• Carefully check that it is guaranteed that the machine is cooled when it is being
commissioned.
4.13.2 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 speci󹪝ed 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 con󹪝guring motor and converter.
• For line voltages (converter input voltages) higher than 480 V, motors have an appropriate
insulation system when ordered for converter operation.
• 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.
