Process Pid Control - GE AF-650 GP Design And Installation Manual

Application Setup Examples

6.5.2 Process PID Control

Process PID control can be used to control application
parameters that can be measured by a sensor (i.e.
pressure, temperature, flow) and be affected by the
connected motor through a pump, fan or otherwise.
The table shows the control configurations where the
process control is possible. When a flux vector motor
control principle is used, take care also to tune the speed
control PID parameters. Refer to the section about the
Control Structure to see where the Speed Control is active.

NOTE!
Process control PID will work under the default parameter
setting, but tuning the parameters is highly recommended
to optimize the application control performance. The two
flux motor control principles are specially dependant on
proper speed control PID tuning (prior to tuning the
process control PID) to yield their full potential.
