In Monitoring Menu, there is a parameter [Motor thermal state] (tHr).
(tSA) [Th.mot. att.]=> Motor thermal state reached
The THR gives the thermal state of the Motor and ttd is the threshold value for the THR
Example: If you program ttd [Motor therm. level] => 90% and R1[R1 Assignment] => tSA,
Then if [Motor thermal state] (tHr) in Monitoring Menu is reached 90% then Relay will change their state.
