K Control Terminals
The signal types of analogue inputs AI1 and AI2 are selected with DIP
switches S1:1 and S1:2, S1 off = voltage signal, S1 on = current signal.
Digital input impedance 1.5 kΩ.
Power terminals: 4 mm
2
single core / torque 0.8 Nm.
Control terminals: Multistrand 0.5 - 1.5 mm
2
(AWG 22...AWG16) / torque 0.4
Nm.
Use 60 °C wire for an ambient temperature of 45 °C or less and use 75 °C
wire for ambient temperature between 45 °C and 50 °C.
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 ACS140
is powered down.
Note! Terminals 3, 6 and 8 are at the same potential.
No. 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 (R
i
= 190 kΩ) (S1:1:U) <=> 0 - 50 Hz output frequency
0- 20 mA (R
i
= 500 Ω) (S1:1:I) <=> 0 - 50 Hz output frequency
Resolution 0.1 % accuracy ±1 %.
3 AGND Analogue input circuit common. (Connected internally to frame earth through
1MΩ.)
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 - 10 V (R
i
= 190 kΩ) (S1:2:U)
0 - 20 mA (R
i
= 500 Ω) (S1:2:I)
Resolution 0.1 % accuracy ±1 %.
6 AGND Analogue input circuit common. (Connected internally to frame earth through
1MΩ.)
7 AO Analogue output, programmable.
Default: 0-20 mA (load < 500 Ω) <=>0-50 Hz
Accuracy: ± 3 % typically.
8 AGND Common for DI return signals.
9 12 V Aux. voltage output 12 V DC / 100 mA (reference to AGND).
Short circuit protected.
10 DCOM Digital input common. To activate a digital input, there must be +12 V
(or -12 V) between that input and DCOM. The 12 V may be provided by the
ACS140 (X1:9) as in the connection examples (see L) or by an external
12-24 V (max 28 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 ACS140.
12 DI 2 Reverse. Activate to reverse rotation
direction.
Stop. Momentary inactivation always
stops the ACS140.
13 DI 3 Jog. Activate to set output frequency
to jogging frequency (default: 5 Hz).
Reverse. Activate to reverse rotation
direction.
14 DI 4 Has to be deactivated. Has to be activated.
15 DI 5 Acceleration/deceleration ramp time selection (default 5 s/ 60 s).
Activate to select 60 s ramp times.
16 RO 1A Relay output 1, programmable (default: fault relay).
Fault: RO 1A and RO 1B not connected.
12 - 250 V AC / 30 V DC, 10 mA - 2 A
17 RO 1B
18 RO 2A Relay output 2, programmable (default: running).
Running: RO 2A and RO 2B connected.
12 - 250 V AC / 30 V DC, 10 mA - 2 A
19 RO 2B
