I/O Configuration - ABB ACS 400V Instructions Manual

I/O Configuration

The following diagram summarizes the I/O connection alternatives given by the ACS 400V.
Input signals
• Start/stop (DI1)
• Control signal 0 - 10 V(AI1)
• Actual value 0 - 10 V, eg. from
pressure sensor (AI2)
• Activate to select PID control
(DI2)
• Select setpoint1/setpoint2 (DI3)
• Constant speed 1 (DI4)
• Constant speed 2 (DI5)

Output signals
• Analogue output AO: Frequency
0 - 50 Hz <=> 0- 20 mA
• Relay output 1: Fault
-> 17 connected to 18
• Relay output 2: Running
-> 20 connected to 22
