Function
This function generates up to 7 values of variation % for the active reference ranging
from –100% to 100% with parameters P115÷P121.
The 3 functions determine which of the 7 values of the speed reference variation is
active: the active value (1) or inactive value (0
) of each preset input signal determines a
bit-logic binary number where SPEED VAR. 0 is the least
significant bit (bit 0), while
SPEED VAR. 2 is the most significant bit (bit 3) as shown in Table 105 and Table 106.
If one of these functions is not set up, its bit is “zero”.

If one of the functions above is not set up, its bit is “zero”.
For example, if C175 and C177 are INACTIVE (0) and C176 is programmed for one terminal, only variation 2
corresponding to parameter P116 can be selected.
In any case, the output speed must never exceed the max. allowable speed, even when a higher speed is required.
NOTE
In Table 106 above:
0 ⇒ Inactive Input;
1 ⇒ Active Input.
