ABB ACS320 - Floating Point

92 Application macros
 Floating point
This application macro is for applications where speed reference needs to be
controlled through digital inputs (DI4 & DI5). By activating digital input 4, the speed
reference increases, by activating digital input 5, the speed reference decreases. If
both digital inputs are active or inactive, the reference does not change.
For more information see Default values with different macros on page 279.
