Pid Control Setpoint Source; Communication Fault; Feedback From The Drive - Fba - Daikin MD5 Operation Manual

PID Control Setpoint Source

Using the fieldbus for the PID control setpoint requires:

Drive Parameter
4010 SETPOINT SEL

Communication Fault

When using fieldbus control, specify the drive's action if serial
communication is lost .

Feedback from the Drive – FBA
Inputs to the controller (drive outputs) have pre-defined
meanings established by the protocol . This feedback does not
require drive configuration. The following table lists a sample of
feedback data . For a complete listing, see all parameters listed
in Complete parameter descriptions .
