• When using an external power supply for transistor output, use terminal PC as a
common to prevent misoperation caused by leakage current.
(Do not connect terminal SD of the inverter with terminal 0V of the external power
supply. When using terminals PC-SD as a 24VDC power supply, do not install the
power supply in parallel outside the inverter. Doing so may cause misoperation due
to leakage current.)
(5) How to use the STOP signal
The following connection example shows how to self-hold the start signals (forward
rotation, reverse rotation).
Use Pr. 180 to Pr. 183 (input terminal function selection) to assign the STOP signal.
