Alternative Acs 400V Operation Modes (Hardwire Connections); Start / Stop And External Control Signal 0-10 V - ABB ACS 400V Instructions Manual

Alternative ACS 400V Operation Modes (Hardwire Connections)

Start / Stop and External Control Signal 0-10 V

• Set DIP switches to voltage signal positions
• Start signal is given by activating DI1 (11)
• Control signal 0-10 VDC from external regulator is connected to AI1 (2, 3)
• Two constant speeds are possible, if 8, 14 and 8, 15 are connected using a switch between 14 and
15, see page 14
