Suppose the electronic thermal setting (B012) is set to 44 Amperes. The left graph below shows
the effect of the free setting torque characteristic curve. For example, at (B017) Hz, the output
current level to cause overheating in a fixed time period is reduced by a factor of (B018). The
right graph below shows the reduced trip current levels in those conditions for given trip times.

Any intelligent output terminal may be programmed to indicate a thermal warning [THM].
Parameter C061 determines the warning threshold. Please see
page 4–52 for more details.
