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.
