3-Wire Macro; Default I/O Connections - ABB ACS350 User Manual

88

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
For the parameter default values, see section
on page 142. If you use other than the default connections presented below, see
section
Note: When the stop input (DI2) is deactivated (no input), the control panel start and
stop buttons are disabled.
