166 ACH580 E-Clipse bypass and packaged drive user manual
Fieldbus adapter
Activate drive control functions – FBA
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. The last column in each table below is deliberately blank. See
the user’s manual supplied with the FBA module for the appropriate entry.
Start/stop control
Using the fieldbus for start/stop/direction control of the drive only requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied command(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
Input reference select
Using the fieldbus to provide input reference to the drive requires:
• Drive parameter value set as defined below.
• Fieldbus controller supplied reference word(s) in the appropriate location. (The
