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.
13 DI1
Digital input 1, programmable. Default
2
= start/stop.
14 DI2
Digital input 2, programmable. Default
2
= not configured.
15 DI3
Digital input 3, programmable. Default
2
= constant (preset) speed.
16 DI4
Digital input 4, programmable. Default
2
= safety interlock.
17 DI5
Digital input 5, programmable. Default
2
= not configured.
18 DI6
Digital input 6, programmable. Default
2
= not configured.
19 RO1C
