＊Regarding interface between inverter and programmable controller In the case programmable controller of open
collector output is used to control the inverter, if the programmable controller is turned off as the power supply to
the inverter is on, such a wrong signal as shown in the following figure flows into the inverter because of
difference in potential of control power. Be sure to provide the system with an interlock so that the programmable
controller cannot be turned off while the inverter is turned on.

★The inverter can be controlled by connecting the
input terminal with output (contactless switch) of a
programmable controller. This input is used for
forward rotation, reverse rotation, preset speed
control, etc. Use a transistor that operates on
24VDC,5mA power.
Operation: Press the START button.
Stop: Press the STOP button.
Switch between forward and reverse
rotation:
Short circuit between S2 and CC.
