6-3 PID Control
The PID control function is a control system that matches a feedback value (i.e., a de-
tected value) to the set target value.
Proportional control, integral control, and derivative control in combination are available
to machinery systems involving redundancy time in control operation. The PID control
function of the 3G3MV Inverter is not suitable to the control of systems that require a
response of 50 ms or quicker, however.
The following description provides the applications and operation of PID control
together with required parameter settings and adjustments.
6-3-1 PID Control Applications
• The following table provides application examples of the Inverter in PID control.
Application Control Sensor used (example)
Speed control The speed data of the machinery system is fed back
so that the operating speed of the machinery
system will coincide with the target value.
The speed data of another machinery system is
input as a target value and the actual operating
speed of the machinery is fed back for synchronous
control.
Tachogenerator
Pressure control Data on pressure is fed back for constant pressure
control.
Pressure sensor
Flow rate control Data on the flow rate of liquid is fed back for precise
flow control.
Flow sensor
Temperature control Data on temperature is fed back for temperature
control using fan operation.
