Learning Protection Features
To receive PTC signal at V1 input terminal, set PRT-35 (Thermal InSrc) to ‗0 (Thermal In)‘
and set the Analog1 input selection switch (SW3) to T1.
To receive PTC signal at I2 input terminal, set PRT-35 (Thermal InSrc) to ‗1 (V2)‘ and set
SW 4 (Analog2 input selection switch) to V2. The sensor does not operate if SW4 is set to
‗I2‘.
When the inverter detects a motor overheat, motor overheat trip occurs with internal delay
time. The trip delay time is not reset instantly when the trip condition is released, but it only
decreases as time passes.
6.1.3 Overload Early Warning and Trip
A warning or fault trip (cutoff) occurs when the motor reaches an overload state, based on
the motor‘s rated current. The amount of current for warnings and trips can be set
separately.
