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

70 Std. 70 EC 700 Std. 700 VC 700 H

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 1 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 342

- [Analog Out1 Sel] to the value “24” (Param Cntl).

— ✔ — ✔✔

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 345

- [Analog Out2 Sel] to the value “24” (Param Cntl).

—— — ✔✔

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 90 -

[Speed Ref A Sel] to the value “22” (DPI Port 5).

✔✔ ✔ ✔✔

AV1 Reference 2 (%) ✔✔ ✔ ✔✔

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

AV3 Output Current (Amps) Read the drive’s output current. ✔✔ ✔ ✔✔
