Thermal Load
This function block provides access to values coming from the motor model. They can be used for further processing or to
connect them to any output block (e.g. bus monitoring).

Parameters
Signal Name
-
Load (W): Thermal load of the motor as a percentage. 100% is the trip level.
Trip: Logical 1 after a thermal overload trip as long as the trip was not acknowledged.
Pre Warn: The output is logical 1 if the thermal load is above a user-defined threshold
Cooling Time Running: Logical 1 as long as the cooling time after a thermal overload trip is
running.
Time to Trip (W): Time in seconds until the motor gets tripped because of thermal
overload.
Time to Restart (W): Time in seconds the user has to wait until the UMC accepts a start
command after a thermal overload trip.
The following parameters define the behaviour of the function block. For more information about the single
parameters see the UMC100 manual (Section: Protection Parameters -> General Protection Parameters).
