Floating Point Macro - ABB Johnson Controls AYK550-UH User Manual

Floating Point macro

This application macro is for applications where speed reference needs to be
controlled through digital inputs (DI5 & DI6). By activating digital input 5, the speed
reference increases, by activating digital input 6, the speed reference decreases. If
both digital inputs are active or inactive, the reference does not change.
Note: When constant speed 1 is activated using digital input 3 (DI3), the reference
speed is the value of parameter 1202. The value remains as the reference speed
when digital input 3 is deactivated.
