BACnet quick-start sequence
The following steps summarize the process for enabling and configuring BACnet on
the ACQ550:
1. Enable BACnet protocol: Set drive parameter 9802,
(5).
Note: If you cannot see the desired selection on the panel, your drive does not have
that protocol software in the application memory.
• To confirm this selection, read drive parameter 5301,
read x5xx (where "x" is any value).
2. Place the BACnet channel in "reset": Set drive parameter 5302,
• This setting holds the BACnet communication channel in reset while remaining
settings are completed.
3. Define the MS/TP baud rate.
• Set drive parameter 5303,
4. Define the Device Object Instance ID.
• To define a specific device object instance value, use drive parameters 5311 and
5317 (object instance values must be unique and in the range 1 to 4,194,303).
• To use the drive's MS/TP MAC ID as the device object instance value, set drive
parameter 5311 and 5317 = 0.
• BACnet requires a unique Device Object ID for each device on the BACnet
network.
5. Define a unique MS/TP MAC ID. Set drive parameter 5302,
appropriate value.
• Once this parameter is set to a non-zero value, current BACnet settings are
"latched" and used for communication until the channel is reset.
