Start / Stop With 2 Constant Speeds - ABB ACS 400V Instructions Manual

Start / Stop with 2 Constant Speeds

• Set DIP switches to voltage signal positions
• Motor starts by activating DI1 (11)
• Two different constant speeds can be set
• Constant speed 1 is set with parameter 1202
• Constant speed 2 is set with parameter 1203
• Constant speed 1 is selected with DI4 (14)
• Constant speed 2 is selected with DI5 (15)
