Operating conditions

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:
ƒ Use sinusoidal filters only together with standard asynchronous machines 0 ... 550 V.
ƒ The operation is only permissible using a V/f or V/f
ƒ The operation is only permissible using a switching frequency of 4 ... 8 kHz.
– The sinusoidal filter overheats when being operated with a switching frequency
< 4 kHz.
– Ensure that the automatic switching frequency reduction is deactivated (see
documentation of the basic device).
ƒ Limit the output frequency to maximally 150 Hz.
ƒ Please note, when dimensioning the controller, that the controller has an additional
load of 10 ... 15 %.
