4.2.4
Multi-step application
You can use the Multi-step speed application with processes where more than 1 fixed frequency ref-
erence is necessary (for example test benches).
It is possible to use 1 + 7 frequency references: 1 basic reference (AI1 or AI2) and 7 preset referenc-
es.
Make a selection of the preset frequency references with digital signals DI4, DI5 and DI6. If none of
these inputs are active, the frequency reference is removed from the analogue input (AI1 or AI2).
Give the start/stop commands from the I/O terminal (DI1 and DI2).
It is possible to configure all the drive outputs freely in all the applications. There are 1 analogue
output (Output Frequency) and 3 relay outputs (Run, Fault, Ready) available on the basic I/O board.
