"B" Group: Fine Tuning Functions
For the following functions, L100-M Series inverters have new ranges or descriptions.

Code SRW Display
B_12 Level of electronic
thermal setting
E-THM LVL 03.00A
B_13 Electronic thermal
characteristic
E-THM CHAR
NOTE: The set value links with the detection current of output current monitor, electric
thermal protection, and overload limit.
The three available electronic thermal characteristic curves are shown in the graph
below.
WARNING: When parameter B_12, level of electronic thermal setting, is set to device
FLA rating (Full Load Ampere nameplate rating), the device provides solid state motor
overload protection at 115% of device FLA or equivalent. Parameter B_12, level of
electronic thermal setting, is a variable parameter.
