ACS 160 User’s Manual 37
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).
Connection example:
*Constant speed selection: 0 = open, 1 = connected
Note! Stop input (DI2) deactivated: panel START/STOP button interlocked (local).
3-wire default parameter values:
Input signals Output signals DIP switch
• Start, stop and direction
(DI1,2,3)
• An. output AO: Frequency
• Analogue reference (AI1) • Relay output 1: Fault
• Preset speed selection (DI4,5) • Relay output 2: Running
