Special operation
Purpose
Perform process control such as
pump and air volume.
Dancer control
Traverse function
Avoid over voltage alarm due to
regeneration by automatic adjust-
ment of output frequency
6.19.1
PID control (Pr. 127 to Pr. 134, Pr. 575 to Pr. 577)
The inverter can be used to exercise process control, e.g. flow rate, air volume or pressure.
The terminal 2 input signal or parameter setting is used as a set point and the terminal 4 input
signal used as a feedback value to constitute a feedback system for PID control.
