0: no application limit
The load display is not influenced by an application-dependent torque reference
with value 0.
16: constant limit
The parameterized value in pn88[2] application reference is the reference value for
the load calculation.

4.4.25.2.3 Thermal limit of the motor (thermal reference)
The setting of thermal reference (bit 6,7) can be used to determine whether the
thermal load of the motor shall also be used for the display of ru80.
For the determination of the thermal rated torque it is assumed that the motor can
also provide rated torque up to rated speed.
For the range above rated speed, it is assumed that the motor can continue supply
rated power permanently without overheating.
The thermal rated torque is therefore equal to the rated torque up to rated speed
and is then reduced according to a 1/x function.
It can be parameterized whether the DC link voltage influences the value of the
thermal load.
4.4.25.3 Resulting display
The maximum value of the 3 loads (motor/inverter, application, thermal load of the
motor) in % with 0.1% resolution is displayed in ru80 relative load.
