Control Terminals - ABB ACS 400 User Manual

J Control Terminals
Main I/O terminal X1
The analog input signal is selected with V/I jumper J1: AI open = V and AI connected = I.
X1 Identification
1 SCR Terminal for signal cable screen. (Connected internally to frame ground.)
2 AI 1 Analog input channel 1, programmable.
Default: 0 - 10 V (R
0 - 20 mA (R
Resolution 0.1 % accuracy ±1 %.
3 AGND Analog input circuit common. (Connected internally to frame ground through 1 MΩ.)
4 10 V 10 V/10 mA reference voltage output for analog input potentiometer, accuracy ±2 %,.
5 AI 2 Analog input channel 2, programmable.
Default: 0 - 20 mA (R
0 - 10 V (R
Resolution 0.1 % accuracy ±1 %.
6 AGND Analog input circuit common. (Connected internally to frame ground through 1 MΩ.)
Analog output, programmable. Default: 0-20 mA (load < 500 Ω) <=>0-f
7 AO1
8 AGND Common for DI return signals.
9 24 V Auxiliary voltage output 24 V DC / 250 mA (reference to AGND).
Short circuit protected.
Digital input common for DI1, DI2 and DI3. To activate a digital input, there must be ≥+10 V
10 DCOM1
(or ≤-10 V) between that input and DCOM1. The 24 V may be provided by the ACS 400
(X1:9) using the connection examples (see Section L) or by an external 12-24 V source of
either polarity.

11 DI 1 Start. Close to start. Motor will ramp up to
frequency reference. Open to stop. Motor will
coast to stop.
12 DI 2 Reverse. Close to reverse rotation direction.
13 DI 3 Jog. Close to set output frequency to jogging
frequency (default: 5 Hz).
14 DI 4 Must be closed for Factory (0).
15 DI 5 Accel/Decel selection (ACC1/DEC1 or ACC2/DEC2).
16 DCOM2 DCOM2 digital input common for DI4, DI5

Digital input impedance 1.5 k
Use multi-strand 0.5-1.5 mm
Note! DI 4 is read only when powered-up (Factory macro (0) and (1)).
Note! For safety reasons the fault relay signals a "fault" when the ACS 400 is powered
down.
