Activate Drive Control Functions – EFB
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 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 document supplied with the
FBA module .
Start/Stop Direction Control
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. (The location is defined 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 field adjustments are recommended.
• 2 .The reference provides direction control – a negative reference provides reverse rotation .
Input Reference Select
Using the fieldbus to provide input references to the drive
requires:
•
Drive parameter values set as defined below.
• Fieldbus controller supplied reference word(s) in the
appropriate location. (The location is defined by the
Protocol Reference, which is protocol dependent .)
