3-Wire Macro; Default I/O Connections - ABB ACS355 User Manual

3-wire macro

This macro is used when the drive is controlled using momentary push-buttons. It
provides three constant speeds. To enable the macro, set the value of parameter
9902 APPLIC MACRO
For the parameter default values, see section
page 176. If you use other than the default connections presented below, see section
I/O terminals on page 51.
Note: When the stop input (DI2) is deactivated (no input), the control panel start and
stop buttons are disabled.
