6-3 PID Control
Detected values of the Inverter in proportional, integral, and derivative
(PID) control are fed back so that the values will coincide with preset target
values.
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, how-
ever.
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.
Tacho generator
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.
Thermocouple
Thermistor
