5-9-9 3-wire Input Function (STA, STP, F/R)
• Use this function to start and stop the inverter via an automatic reset contact such as a pushbutton
switch.
• Allocate the Multi-function Input 1 to 7 Selection (C001 to C007) to 20 (STA), 21 (STP), and 22
(F/R).
• Set the 1st/2nd RUN Command Selection (A002/A202) to 01 (Control circuit terminal block).
• Allocating the terminal STP disables the terminals FW and RV.
• To capture the ON/OFF status reliably, the ON or OFF status must continue for twice the set value of
the input terminal response time (C160 to C166). If the input terminal response time is the default,
ensure that the status continues for 2 ms.
• The operation timing is as follows.
