*1 The function can be changed by switching the RT signal ON/OFF while the inverter is stopped. If a signal is switched during operation, the
operation method changes after the inverter stops. (Pr.450 ≠ 9999)
NOTE
• The RT signal is assigned to terminal RT in the initial status. By setting "3" in any of Pr.178 to Pr.189 (Input terminal function
selection), the RT signal can be assigned to the other terminal.
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

5.9.11 Start signal operation selection

Operation of the start signal (STF/STR) can be selected.
Select the stopping method (deceleration stop or coasting) at turn-OFF of the start signal.
