ABB ACS310, User Manual

Page: 105 / 376

Application macros 105
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 to 2 ( 3-WIRE ).
For the parameter default values, see section Default values with different macros on
page 165 . If you use other than the default connections presented below, see section
I/O terminals on page 49 .
Note: When the stop input (DI2) is deactivated (no input), the control panel start and
stop buttons are disabled.
