Overview
Sine-wave filter
Sine-wave filters limit the rate of voltage rise (
dv/dt
) and the peak
voltages on the motor winding. Similar to an output reactor, they
enable the connection of longer motor cables.
Bearing currents are also reduced significantly. Using these
filters therefore allows standard motors with standard insulation
and without insulated bearings to be operated on SINAMICS.
As a result, the voltage load on the motor winding is virtually
identical to the load on windings of directly mains-fed motors.
Owing to the very low rates of voltage rise on the motor cable,
the sine-wave filter also has a positive impact in terms of electro-
magnetic compatibility which means that it is not absolutely es-
sential to use shielded cables for short motor cables to achieve
the required standard of EMC.
Since the voltage applied to the motor is not pulsed, the inverter-
related stray losses and additional noise in the motor are also
reduced considerably and the noise level of the motor is similar
to the level produced by directly mains-fed motors.
When using sine-wave filters, the following should be observed:
•
Pulse frequencies of between 4 kHz and 8 kHz are
permissible for rated outputs up to and including 90 kW
•
The output frequency is limited to 150 Hz.
•
Operation and commissioning may only be performed with the
motor connected as the sine-wave filter is not no-load proof
•
It must be ensured that the automatic pulse frequency
reduction functions are also deactivated
•
80 % of the line input voltage is available as an output voltage
for PM230 Power Modules.
