Sine filter DX-SIN3… should be operated only 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
For the DA1 variable frequency drive, the set value with the
double-modulation procedure is the double value of the
effective value in the sine filter (1
≙
8 kHz
→
4 kHz;
2
≙
12 kHz
→
6 kHz).
