4.7 Converter operation
4.7.1 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 plate (not the supplementary rating plate with the operating data when
connected to a converter).
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
, on the supplementary plate for converter operation as the highest
speed, or in the type-specific catalog.
● Operate the machine only for a short period at the maximum speed. Operating the
machine for an extended period at the maximum speed may cause vibrations with an
increased frequency and consequently higher noise levels.
● Check that the machine is cooled sufficiently for commissioning purposes.
4.7.2 Reducing bearing currents during operation with converter (low voltage)
Taking the following actions will reduce the bearing currents:
● Ensure that the contacts are established over a large area. Solid copper cables are not
suitable for high frequency grounding because of the skin effect.
Equipotential bonding conductors:
Use equipotential bonding conductors:
● Between motor and driven machine
● Between motor and converter
● Between the terminal box and the RF grounding point at the motor enclosure.
