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 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
2.1.
● Do not exceed the specified maximum speed limit
n
max
. You can either find this on the
rating plate
n
max
or on the supplementary plate for converter operation as the highest
speed.
● Check that the machine is cooled sufficiently for commissioning purposes.
4.14.2 Converter input voltage
The insulation system of SIMOTICS machines significantly exceeds the requirements of
stress category C (IVIC C = high stress). If voltage peaks higher than those specified
according to IVIC C can occur, then observe the data in the respective Catalog
( http://w3app.siemens.com/mcms/infocenter/content/en/Pages/order_form.aspx ):
● For a line voltage (converter input voltage) up to max. 480 V and operation connected to
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.
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.
