Controlling the drive
Fieldbus control of various drive functions requires configuration to:
• Tell the drive (via the bypass) to accept fieldbus control of the function.
• Define as a fieldbus input, any drive data required for control.
• Define as a fieldbus output, any control data required by the drive.
The following sections describe, at a general level, the configuration required for 
each control function. For the protocol-specific details, see the specific protocol 
technical data section in this manual.
