Description
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.
Specified signals can be
output using voltage signals
of 0 to 10 VDC.
This is a common terminal
used by the internal power
supply, digital input and
analog input/output
terminals.
24 VDC power supply for
contact input signal.This is
used as a common terminal
if the source logic is input.
Sink logic input: Shorted
with P24
Source logic input: Shorted
with SC
To drive the contact input
using an external power
supply, remove the shorting
bar. For details, refer to
"Connection to
Programmable Controller
(PLC)" on page 2-22.
Select 7 functions from
among 59, and allocate
them to terminals S1
through S7/EB. Both sink
and source logics are
supported. For details, refer
to "Connection to
Programmable Controller
(PLC)" on page 2-22.
Enabled when the safety
function selector switch is
turned ON. For details, refer
to "Safety Function" on
page 5-167.
