Embedded fieldbus
Activate drive control functions
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.
