CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
Multispeed is used when the selection of up to 8 pre-
programmed speeds are required.
It allows the control of the output speed related to the
values programmed by the parameters P124 to P131,
according to the logical combination of the digital inputs
programmed to multispeed.
Activation of the multispeed function:
-
to ensure that the reference source is given by the
multispeed function, i.e., setting P221=6 for local
mode or P222=6 for remote mode;
- to program one or more digital inputs to multispeed,
according to table below:
The frequency reference is defined by the status of the
digital inputs programmed to multispeed as shown in
table below:
The multispeed function has some advantages for the
stabibilty of the fixed preprogrammed references and the
immunity against electrical noises (digital references and
insulated digital inputs).
