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.)
NOTE: EXT1 = REF1 typically used for follower; EXT2 =
REF2 typically used for PID setpoint.

1. For Modbus, the protocol reference can depend on the prole used, hence two columns in these tables. One column refers to the Daikin Drives prole, selected when parameter 5305 = 0
(Daikin DRV LIM) or 5305 = 2 (Daikin DRV FULL). The other column refers to the DCU prole selected when parameter 5305 = 1 (DCU PROFILE). See Daikin control proles technical data
section.
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:
• Modbus Register 40002 in the Modbus protocol technical
data section.
• Reference scaling in the Daikin control proles technical
data section.
• N2 analog output objects in the N2 protocol technical
data section.
• The slope of points 60 and 61 in the FLN protocol
technical data section.
