C.5 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
(except for H5-parameters):
• 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 S 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 C.1 accordingly to start and stop the drive or set the frequency
reference using BACnet communications.
