Using BACnet Objects 4-3

The type of drive used on the network determines the specific BACnet

objects that are supported. Refer to Table 4.A

for descriptions of the

BACnet objects and the drives supporting those objects.

Compatible PowerFlex Drives

44M40400

Analog Input (AI) Objects

AI0 Analog Input 1 (%) Read the value of Analog Input 1 (voltage or current) on the drive’s I/O

terminal block.

✔✔✔✔

AI1 Analog Input 2 (%) Read the value of Analog Input 2 (voltage or current) on the drive’s I/O

terminal block.

✔✔✔✔

Analog Output (AO) Objects

AO0 Analog Output 1 (%) Read/write the value of Analog Output (PowerFlex 40) or Analog Output 1

(Powerflex 400) on the drive’s I/O terminal block. The drive must be configured

to accept the value of this output from the network. This is done by setting the

following drive parameter:

• PowerFlex 40: A065 - [Analog Out Sel] to the value “18” (Setpnt 0-10), “19”

(Setpnt 0-20) or “20” (Setpnt 4-20)

• PowerFlex 400: T082 - [Analog Out1 Sel] to the value “5” (Setpnt 0-10),

“12” (Setpnt 0-20) or “19” (Setpnt 4-20)

——✔✔

AO1 Analog Output 2 (%) Read/write the value of Analog Output 2 on the drive’s I/O terminal block. The

drive must be configured to accept the value of this output from the network.

This is done by setting drive parameter T085 - [Analog Out2 Sel] to the value

“5” (Setpnt 0-10), “12” (Setpnt 0-20) or “19” (Setpnt 4-20).

———✔

Analog Value (AV) Objects

AV0 Reference 1 (%) Read/write the Reference 1 and Reference 2 values. The drive must be

configured to accept its speed reference from the network. This is typically

done by setting drive parameter P038 - [Speed Reference] to the value “5”

(Comm Port).

✔✔✔✔

AV1 Reference 2 (%) ✔✔✔✔

AV2 Output Frequency (Hz) Read the drive’s output frequency. ✔✔✔✔
