Technical data
Note:
For safety reasons the fault relay signals a “fault” when the ACH550 is
powered down.
X1 Drive Control Terminal Description
1 SCR Terminal for signal cable screen. (Connected internally to chassis ground.)
2 AI1 Analog input channel 1, programmable. Default
2
= external reference. Resolution
0.1%, accuracy ±1%.
J1:AI1 OFF: 0(2)…10 V (R
i
= 312 k

)
J1:AI1 ON: 0(4)…20 mA (R
i
= 100

)
3 AGND Analog input circuit common (connected internally to chassis gnd. through 1 M

).
4 +10 V Potentiometer reference source: 10 V ±2%, max. 10 mA (1k

< R < 10k

).
5 AI2 Analog input channel 2, programmable. Default
2
= PID feedback. Resolution 0.1%,
accuracy ±1%.
J1:AI2 OFF: 0(2)…10 V (R
i
= 312 k

)
J1:AI2 ON: 0(4)…20 mA (R
i
= 100

)
6 AGND Analog input circuit common (connected internally to chassis gnd. through 1 M

).
7 AO1 Analog output, programmable. Default
2
= frequency. 0…20 mA (load < 500

).
Accuracy ±3% full scale.
8 AO2 Analog output, programmable. Default
2
= current. 0…20 mA (load < 500

).
Accuracy ±3% full scale.
9 AGND Analog output circuit common (connected internally to chassis gnd. through 1 M

).
10 +24V Auxiliary voltage output 24 VDC / 250 mA (reference to GND), short circuit
protected.
11 GND Auxiliary voltage output common (connected internally as floating).
12 DCOM Digital input common. To activate a digital input, there must be

10 V
(or

-10 V) between that input and DCOM. The 24 V may be provided by the
ACH550 (X1-10) or by an external 12…24 V source of either polarity.

2
= not configured.
18 DI6 Digital input 6, programmable. Default
2
= not configured.
19 RO1C Relay output 1, programmable. Default
