Analog output control
Using the fieldbus for analog output control (e.g. PID setpoint) requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied analog value(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)

PID control setpoint source
Using the fieldbus for the PID control setpoint requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied setpoint value in the appropriate location.
Drive Parameter
40.16
40.17
40.18
40.92
NOTE: For 41.16 – 41.18, PID set 2 can be used. Setpoint data storage still uses 40.92, even when
PID set 2 is used.
