(1) PTC / NTC thermistor used to
protect the motor can be connected.
Switch SW5 (refer to 6.6) on the
board to the PTC / NTC side.
The internal circuitry of switching
SW5 (switch of terminal AUI)
to the PTC / NTC side is shown
in the right figure. Refer to
“Transfer of various switches
in 6.6” for the details of SW5.
Change function parameter 04.26
accordingly when switching SW5
to the PTC / NTC side.
