Protection functions

The temperature protection using the RTD sensors can be done using the function

block. The measured temperature can be fed from the RTD sensor to the function

input that detects too high temperatures in the motor bearings or windings, for

example. When the ENA_ADD input is enabled, the threshold value of the internal

comparator is the sum of the

temporal increase or decrease of the level detector depending on the sign and value

If, for example,

active, the input signal needs to rise above 120 before MAPGAPC operates.
