Control terminals table
The following provides information for connecting control wiring at X1 on the drive.
Installation
X1
1 SCR Terminal for signal cable shield (screen). (Connected internally to chassis ground.)
2 AI1 Analog input channel 1, programmable. Default
0.1%, accuracy ±1%.
Two different DIP switch types can be used.
J1: AI1 OFF: 0...10 V (R
J1: AI1 ON: 0...20 mA (R
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
accuracy ±1%.
Two different DIP switch types can be used.
J1: AI2 OFF: 0...10 V (R
J1: AI2 ON: 0...20 mA (R
6 AGND Analog input circuit common (connected internally to chassis gnd. through 1 Mohm).
7 AO1 Analog output, programmable. Default
Accuracy ±3%.
8 AO2 Analog output, programmable. Default
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
14 DI2 Digital input 2, programmable. Default
15 DI3 Digital input 3, programmable. Default
16 DI4 Digital input 4, programmable. Default
17 DI5 Digital input 5, programmable. Default
18 DI6 Digital input 6, programmable. Default
