Range
P133 to P134
Multispeed is used when the selection of up to 8 pre-
[ 3.0Hz ]
programmed speeds are required.
It allows the control of the output speed related to the
1Hz (>99.9Hz)
values programmed by the parameters P124 to P131,
according to the logical combination of the digital inputs
P133 to P134
programmed to multispeed.
[ 10.0Hz ]
Activation of the multispeed function:
-
1Hz (>99.9Hz)
P133 to P134
[ 20.0Hz ]
-
1Hz (>99.9Hz)
P133 to P134
[ 30.0Hz ]
1Hz (>99.9Hz)
P133 to P134
[ 40.0Hz ]
The frequency reference is defined by the status of the
digital inputs programmed to multispeed as shown in
1Hz (>99.9Hz)
table below:
P133 to P134
[ 50.0Hz ]
1Hz (>99.9Hz)
P133 to P134
[ 60.0Hz ]
1Hz (>99.9Hz)
P133 to P134
[ 66.0Hz ]
1Hz (>99.9Hz)
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).
Description/Notes

multispeed function, i.e., setting P221=6 for local
mode or P222=6 for remote mode;
