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 find parameter data here:
– In the converter operating instructions
– In the TIA selection tool
– In the SINAMICS Configuration 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
speed limit is n
supplementary plate for converter operation as the highest or lowest specified speed.
• Carefully check that it is guaranteed that the machine is cooled when it is being
commissioned.
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 (Page 13).
• 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.
• 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.
NOTICE
Material damage caused by an excessively high supply voltage
The insulation system will be damaged if the supply voltage is too high for the insulation
system. This can completely destroy the machine.
• Comply with the peak voltages as laid down in the guidelines above.
