Example
If,
N1 = 300 rpm, defined by parameter 37.11 ULC speed table point 1
N2 = 600rpm, defined by parameter 37.12 ULC speed table point 2
OL1 = 10%, defined by parameter 37.31 ULC overload point 1
OL2 = 20%, defined by parameter 37.32 ULC overload point 2
Parameter 37.03 = Warning
Overload axis = torque%, defined by parameter 37.02 ULC supervision signal
Drive speed = 450 rpm,
the drive generates A8BE (Aux code 0001) warning, if the actual torque exceeds 15%
(calculated by leaner interpolation between point (N1, OL1) and (N2, Ol2) for the
predefined time), after the time period mentioned in parameter 37.41 ULC overload
timer.
If the parameter 37.03 is set as Disabled, the drive does not generate any warning.

 Process PID control
There are two built-in process PID controllers (PID set 1 and PID set 2) in the drive.
The controller can be used to control process variables such as pressure or flow in
the pipe or fluid level in the container.
In process PID control, a process reference (setpoint) is connected to the drive
instead of a speed reference. An actual value (process feedback) is also brought
back to the drive. The process PID control adjusts the drive speed in order to keep
the measured process quantity (actual value) at the desired level (setpoint). This
means that user does not need to set a frequency/speed/torque reference to the drive
but the drive adjust its operation according to the process PID.
The simplified block diagram below illustrates the process PID control. For more
detailed block diagrams, see pages 495 and 498.
