connecting the motor signal wire to one of the
inverter’s analog input terminals allows the
inverter to detect the changes in the PTC resistance and translates it into voltage. If the I2
terminal is used to receive the signal, set the selection switch on the I/O board to V2. If the
V1 terminal is used, set the switch to T1.
The sensor does not operate if SW3 is set to’ V1’.
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.
