Daikin MD5 - PID Control Setpoint Source; Communication Fault; Feedback from the Drive - FBA

PID Control Setpoint Source
Using the eldbus for the PID control setpoint requires: • Drive parameter values set as dened below.
• Fieldbus controller supplied setpoint value in the
appropriate location. (As dened in Analog output control
above.)
Table 50: Setpoint Values
Drive Parameter Value Description Protocol Reference
4010 SETPOINT SEL
8 (COMM VALUE 1)
9 (COMM + AI1)
10 (COMM*AI1)
Setpoint is 0135 value (+/-/* AI1) —
Communication Fault
When using eldbus control, specify the drive’s action if serial
communication is lost.
Table 51: Communication Fault
Drive Parameter Value Description Protocol Reference
3018 COMM FAULT FUNC
0 (NOT SEL)
1 (FAULT)
2 (CONST SP7)
3 (LAST SPEED)
Set for appropriate drive response. —
3019 COMM FAULT TIME
Set time delay before
acting on a communication
loss.

Feedback from the Drive – FBA
Inputs to the controller (drive outputs) have pre-dened
meanings established by the protocol. This feedback does not
require drive conguration. The following table lists a sample of
feedback data. For a complete listing, see all parameters listed
in Complete parameter descriptions.
Scaling
To scale the drive parameter values see the Actual value
scaling in the following sections, as appropriate:
• Daikin drives prole technical data
• Generic prole technical data
