Application range
A sinusoidal filter (LC filter) in the motor cable limits the rate of rise of voltage and the
capacitive charge/discharge currents which occur during inverter operation. This enables
considerably longer shielded motor cables and the service life of the motor is increased.
The following must be observed when using sinusoidal filters:
ƒ Use sinusoidal filters only together with standard asynchronous machines 0 ... 550 V.
ƒ Operation is only permissible using a V/f or V/f 2 characteristic control.
ƒ Operation is only permissible using a switching frequency of 2 ... 4 kHz.
– Ensure that the automatic switching frequency reduction is deactivated (see
documentation of the standard device).
ƒ Limit the output frequency to maximally 90 Hz.
ƒ Please note, when dimensioning the controller, that the controller has an additional
load of 10 ... 15 %.
