Table 62: Drive Control Terminal Descriptions
X1 Drive Control Terminal Description
Analog I/O
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 (Ri = 312 kΩ) or, for OFF for ON
J1:AI1 ON: 0(4)…20 mA (Ri = 100 Ω)
3 AGND Analog input circuit common (connected internally to chassis gnd. through 1 MΩ).
4 +10 V Potentiometer reference source: 10 V ±2%, max. 10 mA (1kΩ < R < 10kΩ).
5 AI2
Analog input channel 2, programmable . Default
2
= PID feedback . Resolution 0 .1%, accuracy ±1% .
J1:AI2 OFF: 0(2)…10 V (Ri = 312 kΩ) or, for OFF for ON
J1:AI2 ON: 0(4)…20 mA (Ri = 100 Ω)
6 AGND Analog input circuit common (connected internally to chassis gnd. through 1 MΩ).
7 AO1 Analog output, programmable . Default
2
= frequency. 0…20 mA (load < 500 Ω).
8 AO2 Analog output, programmable . Default
2
= current. 0…20 mA (load < 500 Ω).
9 AGND Analog output circuit common (connected internally to chassis gnd. through 1 MΩ).
Digital Inputs
1
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 MD5 (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.

26 RO3A
27 RO3B
1 Digital input impedance 1.5 kΩ. Maximum voltage for digital inputs is 30 V.
2 Default values depend on the macro used. Values specified are for the HVAC default macro. See Application Macros on page 9 .
You can wire the digital input terminals in either a PNP or NPN
configuration.
Serial Communications
Terminals 28…32 provide RS485 serial communication
connections used to control or monitor the drive from a fieldbus
controller . See Embedded Fieldbus on page 45 for details .
