input
S5/TH External
thermistor input
(also used as
multi-function
input terminal)
Connect an external
thermistor between the
SCs, to trip the Inverter
when a temperature error
occurs. (The inverter will trip
when the input from
thermistor is approx. 3 kΩ or
higher.) Since this input is
also used as the multi-
function input terminal,
setting of C005 is required.
For details, refer to
"Thermistor Trip Function"
on page 5-120.

24 VDC power supply for
contact input signal.This is
used as a common terminal
if the source logic is input.
