Identification Description:
1 SCR Terminal for signal cable screen. (Connected internally to frame earth.)
2 AI 1 Analogue input channel 1, programmable.
Default: 0 - 10 V (Ri
= 200 kΩ) (J1:AI1 open) <=> 0 - 50 Hz frequency reference
0 - 20 mA (Ri
= 500 Ω) (J1:AI1 closed) <=> 0 - 50 Hz frequency reference
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 (Ri
= 500 Ω) (J1:AI2 closed)
0 - 10 V (Ri
= 200 kΩ) (J1:AI2 open)
Resolution 0.1 % accuracy ±1 %.
6 AGND Analogue input circuit common. (Connected internally to frame earth through 1 MΩ.)
7 AO1 Analogue output, programmable. Default: 0 - 20 mA (load < 500 Ω) <=> 0 - 50 Hz output
frequency. Accuracy: ±3 % typically.
8 AGND Common for DI return signals. (Connected internally to frame earth through 1 MΩ.)
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) Factory (1)
11 DI 1 Start. Activate to start. Motor will ramp up to
frequency reference. Disconnect to stop.
Motor will coast to stop.
Start. If DI 2 is activated, momentary
activation of DI 1 starts the ACS 400.
12 DI 2 Reverse. Activate to reverse rotation
direction.
Stop. Momentary inactivation always stops
the ACS 400.
13 DI 3 Jog. Activate to set output frequency to
jogging frequency (default: 5 Hz).
Reverse. Activate to reverse rotation
direction.
14 DI 4 Must be deactivated for Factory 0). Must to be activated for Factory (1).
15 DI 5 Ramp pair selection (ACC1/DEC1 or ACC2/DEC2).
16 DCOM2 DCOM2 digital input common 2 for DI4, DI5
17 RO1C Relay output 1, programmable (default operation: fault => 17 connected to 18).
12 - 250 V AC / 30 V DC, 10 mA - 2 A 18 RO1A
19 RO1B
20 RO2C Relay
