8 Drive Operations by BACnet
The drive operations that can be performed by BACnet communication depend on drive
parameter settings. This section explains the functions that can be used and related parameter
settings.
u Observing the Drive Operation
A controller can perform the following actions with BACnet communications at any time
regardless of parameter settings:
• observe drive status and drive control terminal status from a controller
• read and write parameters
• set and reset faults
• set multi-function inputs.
Note: Input settings from the input terminals So and from BACnet communications are both linked by a logical
OR operation.
u Controlling the Drive
Select an external reference and adjust the parameters in Table 8 accordingly to start and stop
the drive or set the frequency reference using BACnet communications.
