Analog Output Control; Pid Control Setpoint Source; Communication Fault - Daikin MD5 Operation Manual

Analog Output Control

Using the fieldbus for analog output control 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 .)

PID Control Setpoint Source

Use the following settings to select the fieldbus as the setpoint source for PID loops:

Communication Fault

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