3.2.5 Multi-purpose application
You can use the Multi-purpose application for different processes (for example conveyors)
where a wide range of motor control functions is necessary.
It is possible to control the drive from the keypad, Fieldbus or I/O terminal. When you use I/O
terminal control, the start/stop commands are given through DI1 and DI2, and the frequency
reference from AI1 or AI2.
There are 2 acceleration/deceleration ramps available. The selection between Ramp1 and
Ramp2 is made by DI6.
It is possible to configure all the drive outputs freely in all the applications. There are 1 ana-
logue output (Output Frequency) and 3 relay outputs (Run, Fault, Ready) available on the basic
I/O board.

Type of U/f curve between
zero frequency and the field
weakening point.
0=Linear
1=Squared
2=Programmable
P1.35.7 Field WeakngPnt 8.00 P3.3.1.2 Hz Varies 602
The field weakening point is
the output frequency at
which the output voltage
reaches the field weakening
point voltage
P1.35.8 Voltage at FWP 10.00 200.00 % 100.00 603
Voltage at field weakening
point in % of motor nominal
voltage
P1.35.9 U/f Mid Freq 0.00 P3.1.4.2 Hz Varies 604
Provided that the program-
mable U/f curve has been
selected (par. P3.1.4.1) , this
parameter defines the mid-
dle point frequency of the
curve.
