This function is only valid in speed sensor vector control.
Inverter fault alarms when deviation detected between motor actual Speed and the set
frequency(deviation

F9.70). Fault No. 42=Err42.
F9.70=0.0s

PID control is a common method used in process control. Through the proportional,
integration and differential calculation on the difference between feedback signal and target signal
of the controlled parameter, PID control adjusts the output frequency of the inverter and forms
negative feedback system, making the controlled parameter stabilized on the target parameter.
PID control is appliedto several process controls such as flow control, pressure control and
temperature control.The schematic diagram for control is as shown in Fig. 5-25.

It is used to select target parameter reference channel of process PID.
Set target value of process PID is a relative value, set range is 0.0%~100.0%. PID feedback value is a
relative value as well,PID play the role of making the two relative value the same.
