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.

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.
Description
Terminal for signal cable screen. (Connected internally to frame earth.)
Analogue input channel 1, programmable.
Default: 0 - 10 V (R
= 500 Ω) (S1:1:I) <=> 0 - 50 Hz output frequency
0- 20 mA (R

Resolution 0.1 % accuracy ±1 %.
Analogue input circuit common. (Connected internally to frame earth through
1 MΩ.)
10 V/10 mA reference voltage output for analogue input potentiometer,
accuracy ±2 %.
Analogue input channel 2, programmable.
Default: 0 - 10 V (R
= 500 Ω) (S1:2:I)
0 - 20 mA (R
i
Resolution 0.1 % accuracy ±1 %.
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
Accuracy: ± 3 % typically.
Common for DI return signals.
Aux. voltage output 12 V DC / 100 mA (reference to AGND).
Short circuit protected.
Digital input common. To activate a digital input, there must be
(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.

Start. Activate to start. Motor will
ramp up to frequency reference.
Disconnect to stop. Motor will coast to
stop.
Reverse. Activate to reverse rotation
direction.
Jog. Activate to set output frequency
to jogging frequency (default: 5 Hz).
Has to be deactivated.
Acceleration/deceleration ramp time selection (default 5 s/ 60 s).
Activate to select 60 s ramp times.

Start. If DI 2 is activated, momentary
activation of DI 1 starts the ACS140.
Stop. Momentary inactivation always
stops the ACS140.
Reverse. Activate to reverse rotation
direction.
Has to be activated.
Relay output 1, programmable (default: fault relay).
Fault: RO 1A and RO 1B not connected.
