E.14.4 Relay output control
Using the fi eldbus for relay output control requires:
• drive parameter values set as defi ned below
• fi eldbus controller command(s) in the appropriate location. (The location is defi ned by the Protocol Reference, which is
protocol dependent.)

E.14.5 Analog output control
Using the fi eldbus for analog output control (e.g. PID setpoint) requires:
• drive parameter values set as defi ned below
• fi eldbus controller command(s) in the appropriate location. (The location is defi ned by the Protocol Reference, which is
protocol dependent.)
