Application macros
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
to 2 (3-WIRE).
For the parameter default values, see section
Default values with different macros
. 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.
