Sine filter DX-SIN3… should only be operated with fixed
switching frequencies.
Accordingly, the switching frequency (P2-24) must be set to the
value set in parameter P6-02 (auto temperature management)
(P2-24 = P6-02).
Permissible switching frequencies for DA1 with DX-SIN3…:
1 8 kHz; 2 12 kHz
As a result of double modulation, the value set on the DA1
variable frequency drive will be twice the effective value on the
sine filter (1 8kHz
4 kHz; 2 12 kHz 6 kHz).
