The error value of the PID controller. It is the devi-
ation of feedback from the setpoint in process
units. You can use a parameter to make the selec-
tion of the process unit.
The PID output as a percentage (0-100%). It is pos-
sible to give this value to the motor control (fre-
quency reference) or to an analogue output.
