Activate Drive Control Functions – EFB
Controlling the Drive
Fieldbus control of various drive functions requires
conguration to:
• Tell the drive to accept eldbus control of the function.
• Dene as a eldbus input, any drive data required for
control.
• Dene as a eldbus output, any control data required by
the drive.
The following sections describe, at a general level, the
conguration required for each control function. For the
protocol-specic details, see the document supplied with the
FBA module.
Start/Stop Direction Control
Using the eldbus for start/stop/direction control of the drive
requires:
• Drive parameter values set as dened below.
• Fieldbus controller supplied command(s) in the
appropriate location. (The location is dened by the
Protocol Reference, which is protocol dependent.)

• 1.Daikin MicroTech II controls communicate with the MD4 over Modbus and all parameters are factory set. No eld adjustments are recommended.
• 2.The reference provides direction control – a negative reference provides reverse rotation.
Input Reference Select
Using the eldbus to provide input references to the drive
requires:
• Drive parameter values set as dened below.
• Fieldbus controller supplied reference word(s) in the
appropriate location. (The location is dened by the
Protocol Reference, which is protocol dependent.)

Reference Scaling
Where required, REFERENCES can be scaled. See the following, as appropriate:
