Vacon 100 flow Applications Manual

The value in process units at a 0% feedback or setpoint. This scaling is done for monitoring
purposes only. The PID controller still uses the percentage internally for feedbacks and
setpoints.
P3.13.1.8 ERROR INVERSION (ID 340)
Use this parameter to invert the error value of the PID controller.
P3.13.1.9 DEAD BAND (ID 1056)
Use this parameter to set the dead band area around the PID setpoint value.
The value of this parameter is given in the selected process unit. The output of the PID
controller is locked if the feedback value stays in the dead band area for the set time.
P3.13.1.10 DEAD BAND DELAY (ID 1057)
Use this parameter to set the time that the feedback value must stay in the dead band area
before the output of the PID controller is locked.
If the actual value stays in the dead band area for a time set in Dead Band Delay, the PID
controller output is locked. This function prevents wear and unwanted movements of the
actuators, for example valves.
