When frequency source is chosen to be PID, i.e. F0.03 is chosen to be 5, these group
functions are active.
This parameter is to determine the assignment channel of the process PIDtarget value.
The set target value of process PID is a relative value, and the set 100%is corresponding to
the 100% feedback signal of the system being controlled.
The system always performs the calculation according to relative value (0-100%)
Note: If multistage input, it can be accomplished by means of setting F4 group parameters.

When F4.08=0 is chosen, i.e. the target source is the keyboard, it is required to set this
parameter.
The reference value of this parameter is the system feedback value.
