Operating conditions

A sinusoidal filter (LC filter) in the motor cable limits the rate of rise of voltage
(du/dt < 500 V/ms) and the capacitive charge/discharge currents which occur
during inverter operation. This enables considerably larger shielded motor
cables and the service life of the motor is increased.
The following must be observed when using sinusoidal filters:
Use sinusoidal filters only together with standard asynchronous
ƒ
machines 0 ... 550 V.
Operation is only permissible using a V/f or V/f
ƒ
Operation is only permissible using a switching frequency of 2 ... 4 kHz.
ƒ
–
Ensure that the automatic switching frequency reduction is deactivated
(see documentation of the standard device).
Limit the output frequency to maximally 90 Hz.
ƒ
Please note, when dimensioning the controller, that the controller has an
ƒ
additional load of 10 ... 15 %.
