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
macros
see section
Note: When the stop input (DI2) is deactivated (no input), the control panel start and
stop buttons are disabled.
