j) MULTISPEED
The Multispeed reference, as described in Section 7.2 SPEED REFERENCE on page 7-6, enables, by means
of the combination of up to three digital inputs, the selection of one from eight reference levels predefined in
parameters P124 to P131.
For further details, refer to Chapter 7 COMMAND AND REFERENCES on page 7-1.
k) 2
nd
RAMPA
If DIx is inactive, the inverter uses the default ramp by P100 and P101, otherwise, it will use the 2
nd
Ramp by
P102 and P103 (Figure 9.14 on page 9-18).
