X1 Identification
1 SCR Terminal for signal cable screen. (Connected internally to frame earth.)
2 AI 1 Analogue input channel 1, programmable.
Default: 0 - 10 V (R
0 - 20 mA (R
Resolution 0.1 % accuracy ±1 %.
3 AGND Analogue input circuit common. (Connected internally to frame earth through 1 MΩ.)
4 10 V 10 V/10 mA reference voltage output for analogue input potentiometer, accuracy ±2 %.
5 AI 2 Analogue input channel 2, programmable.
Default: 0 - 20 mA (R
0 - 10 V (R
Resolution 0.1 % accuracy ±1 %.
6 AGND Analogue input circuit common. (Connected internally to frame earth through 1 MΩ.)
Analogue output, programmable. Default: 0 - 20 mA (load < 500 Ω) <=> 0 - 50 Hz output
7 AO1
frequency.
8 AGND Common for DI return signals.
9 24 V Auxiliary voltage output 24 V DC +20 %, -10 % / 250 mA (reference to AGND).
Short circuit protected.
10 DCOM1 Digital input common 1 for DI1, DI2 and DI3. To activate a digital input, there must be
≥+10 V (or ≤-10 V) between that input and DCOM1. The 24 V may be provided by the
ACS 400 (X1:9) as in the connection examples (see L) or by an external 12 - 24 V source
of either polarity.
DI Configuration Factory (0)
11 DI 1 Start. Activate to start. Motor will ramp up to
frequency reference. Disconnect to stop.
Motor will coast to stop.
12 DI 2 Reverse. Activate to reverse rotation
direction.
13 DI 3 Jog. Activate to set output frequency to
jogging frequency (default: 5 Hz).
14 DI 4 Must be deactivated for Factory 0).
15 DI 5 Ramp pair selection (ACC1/DEC1 or ACC2/DEC2).
16 DCOM2 DCOM2 digital input common 2 for DI4, DI5
17 RO1C
18 RO1A
19 RO1B
20 RO2C
21 RO2A
22 RO2B
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 fail safe reasons the fault relay signals a "fault", when the ACS 400 is powered down.

Description
Factory (1)
Start. If DI 2 is activated, momentary
activation of DI 1 starts the ACS 400.
Stop. Momentary inactivation always stops
the ACS 400.
Reverse. Activate to reverse rotation
direction.
Must to be activated for Factory (1).
