Application macros
3-wire macro
This macro is used when the drive is controlled using momentary push-buttons. It
provides three (3) constant speeds. To enable, set the value of parameter 9902 to
2 (3-
WIRE
).
Note: When the stop input (
DI
2) is deactivated (no input), the control panel start/stop
buttons are disabled.
