3.3 PID Control Application

Use the PID control application with processes where the process variable (for example pressure) is controlled through control of
the speed of the motor.
In this application, the internal PID controller of the drive is configured for 1 setpoint and 1 feedback signal.
It is possible to use 2 control places. Make the selection of the control place A or B with DI6. When control place A is active, the start/
stop commands are given by DI1, and the PID controller gives the frequency reference. When control place B is active, start/stop
commands are given by DI4, and AI1 gives the frequency reference.
It is possible to configure all the drive outputs freely in all the applications. There are 1 analog output (Output Frequency) and 3
relay outputs (Run, Fault, Ready) available on the basic I/O board.
