80 Chapter 7 - Parameters Description
User Manual
Drive behaviour around minimum values
P.081
settings in A condition
Giving the RUN command, the motor will rich the frequency set of
P.081
(A) without to follow the setting of
acceleration ramp time.
The reference action on the frequency curve, will have effect starting from the setting value of
P.081
parameter.
P.081
settings in B condition
Giving the RUN command, the motor will rich the frequency set of
P.081
(B) without to follow the setting of
acceleration ramp time.
The increasing of the reference will have effect on the frequency output, starting from the setting value of
F.021
parameter (the variation will follow the setting of acceleration ramp time).
The reference action on the frequency curve, will have effect starting from the setting value of
F.021
parameter.
The
Max output freq (P.080)
and the
Min output freq (P.081)
are expressed as percentage of the values of
Max ref freq (F.020)
.

Reference Sources
F.050 Ref 1 Channel
(Reference 1 channel)
F.051 Ref 2 Channel
(Reference 2 channel)
As shown in the figure 7.5.1, the Sources from which the 2 speed references are provided and controlled, can be
chosen by following the table below.
The value of the 2 references, will always be an algebric sum.
F.060 Mlt Frq Channel 1
(Multi frequency channel 1)
F.061 Mlt Frq Channel 2
(Multi frequency channel 2)
These parameters allow to select the source, from where the
First
and
Second
frequency reference of the
Multispeed function
,
can be provided and controlled (See figure 7.5.1).
The source can be chosen the following parameters the table below.
