Controlling the drive
Fieldbus control of various drive functions requires configuration to:
• Tell the drive to accept fieldbus control of the function.
• Define as a fieldbus input, any system data required for control (drive only or
system)
• Define as a fieldbus output, any control data required by the drive.
The following sections describe the configuration required for each control function.
Note: The user should change only the parameters for the functions you wish to
control via BACnet. All other parameters should typically remain at factory default.
Start/stop direction control – Drive
Using the fieldbus for start/stop/direction control of the drive requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied command(s) in the appropriate location.
