ACS 400 User’s Manual 57
Application Macro 3-wire
This macro is intended for those applications where the drive is controlled using momentary push-
buttons. It gives two more preset speeds compared to Factory Macro (1) by using DI4 and DI5.
The value of parameter 9902 is 2 (3-
WIRE).
*Constant speed selection: 0 = open, 1 = connected
Note! Stop input (DI2) deactivated: panel START/STOP button interlocked (local).
Application Macro 3-wire parameter values:
