ACS550 User's Manual

Application Macro: 3-wire

This macro is used when the drive is controlled using momentary push-buttons, and
provides three (3) constant speeds. To enable, set the value of parameter 9902 to 2
(3-
WIRE
Note! When the stop input (
buttons are disabled.
Connection example:
• Analog reference (AI1)
• Start, stop and direction (DI1,2,3)
• Constant speed selection (DI4,5)
).
