Default
C155 = 4, C156 = 5,
C157 = 0, C158 = 0.
C155 = MDI4, C156 = MDI5,
C157 = C158 = Inactive.
Function
This function generates up to 15 speed references that can be programmed with
parameters P081÷P098 according to the programming mode set in P080.
The 4 Multispeed functions determine whic
h of the 15 active speed references are
active: active value (1) or inactive value (0
) of each preset input signal determines a
bit-logic binary number: MULTISPEED 0 is the least
significant bit (bit 0) and
MULTISPEED 3 is the most significant bit (bit 3).
If one of these functions is not set up, its relevant bit is “zero”.

If one of these functions is not set up, its relevant bit is “zero”.
For example, if C156 and C157 are Inactive (0), while C155 and C158 are programmed to two different terminals, only
Multispeed 0, 1, 8, 9 can be selected, relating to the following references:
(*) Factory-setting: (P080 = Preset Speed) if no Multispeed function is selected, the active reference is the reference
set according to the parameters in the INPUTS FOR REFERENCES MENU.
If P080 = Speed Sum, the selected Multispeed function adds up to the active reference: the reference set according to
the parameters in the INPUTS FOR REFERENCES MENU.
If P080 = Preset Speed Esc, the selected Multispeed replaces the active reference, which will be ignored. If no
Multispeed function is selected, the resulting reference is equal to zero.
See also the INPUTS FOR REFERENCES MENU for the reference processing sequence: the Speed Decrease function
and the Reference Reversal function become active downstream of the Multispeed function.
