The following provides information for connecting control wiring at X1 on the drive.
X1 Hardware description
1 SCR Terminal for signal cable screen. (Connected internally to chassis ground.)
2 AI1 Analog input channel 1, programmable. Default
2
= frequency reference. Resolution
0.1%, accuracy ±1%.
Two different DIP switch types can be used.
J1: AI1 OFF: 0…10 V ( R
i
= 312 kohm)
J1: AI1 ON: 0…20 mA ( R
i
= 100 ohm)
3 AGND Analog input circuit common (connected internally to chassis gnd. through 1 Mohm).
4 +10 V Potentiometer reference source: 10 V ±2%, max. 10 mA (1 kohm < R < 10 kohm).
5 AI2 Analog input channel 2, programmable. Default
2
= not used. Resolution 0.1%,
accuracy ±1%.
Two different DIP switch types can be used.
J1: AI2 OFF: 0…10 V ( R
i
= 312 kohm)
J1: AI2 ON: 0…20 mA ( R
i
= 100 ohm)
6 AGND Analog input circuit common (connected internally to chassis gnd. through 1 Mohm).
7 AO1 Analog output, programmable. Default
2
= frequency. 0…20 mA (load < 500 ohm).
Accuracy ±3%.
8 AO2 Analog output, programmable. Default
2
= current. 0…20 mA (load < 500 ohm).
Accuracy ±3%.
9 AGND Analog output circuit common (connected internally to chassis gnd. through 1 Mohm).
10 +24V Auxiliary voltage output 24 V DC / 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
ACS550 (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
= fwd/rev.
15 DI3 Digital input 3, programmable. Default
2
= constant speed sel (code).
16 DI4 Digital input 4, programmable. Default
2
= constant speed sel (code).
17 DI5 Digital input 5, programmable. Default
2
= ramp pair selection (code).
18 DI6 Digital input 6, programmable. Default
2
= not used.
