Functions Common to All the Control Modes
Description:
The Multispeed brings as advantages the stability of the predefined fixed references, and the immunity against
electric noises (isolated digital inputs DIx).
In order to activate the Multispeed function one must configure the parameter P0221=8 and/or P0222=8
(Reference Selection).
In order to use only 2 or 4 speeds, any combination of the DI4, DI5 and DI6 inputs can be used. Verify the Speed
Reference parameters according to the used DI's.
The input(s) programmed for other function(s) must be considered as 0 V, as presented in the table 12.4.
