NOTE!
The value programmed for motor overtemperature alarm reset
must be lower that the value programmed for alarm actuation
level.
It programs the level of motor overtemperature alarm reset.
Normally a value 30% below of the insulation class of the motor
is used.
 If the motor overtemperature alarm is active and the motor
temperatura value is lower than the reset level, the indication of
the alarm will be removed.

the error message in the HMI. In case that it is programmed for
alarm, the motor continues running and will be indicated the mes-
sage of alarm in the display of the HMI.
Table 6.53 - Fault sensor action selection
 It allows selecting the protection trip between Fault and Alarm.
 The Fault trips disabling the motor when the thermal protection
reaches the maximum level (250%). It only leaves this condition
through the Reset. This condition can be indicated via digital output.
