296 Fieldbus control
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.
