*4 To use the signal, assign the function to the output terminal Pr.190 to Pr.195 (Output terminal function selection) of the converter unit. Always
set the negative logic for the ALM signal.
NOTE
• To use the electronic bypass function, the wiring terminals R1/L11 and S1/L21 must be connected to a separate power source
that does not go through MC1. Be sure to connect using a separate power supply.
• Be sure to provide a mechanical interlock for MC2 and MC3.
• Operation of magnetic contactor (MC1, MC2, MC3)

RES RES
Set "95 or 96" in any
X95/X96 parameter from
Pr.180 to Pr.189.
*1 For separated converter types, the X10 signal is assigned to the terminal MRS in the initial setting. For the MRS signal, set "24" to any of Pr.180
to Pr.189 (Input terminal function selection) to assign the function to another terminal.
*2 When the MRS signal is OFF, neither the commercial power supply operation nor the inverter operation can be performed.
*3 Terminal CS is initially set to "no function". To enable the CS signal, set "6" in Pr.186 CS terminal function selection to assign the function to
a terminal. The CS signal operates only when the MRS signal is ON.
*4 STF (STR) operates only when the MRS and CS signals are both ON.
*5 The RES signal can be used for reset input acceptance with Pr.75 Reset selection/disconnected PU detection/PU stop selection. When the
RES signal and another input signal are simultaneously input, the MC operation by the RES signal has a higher priority.
*6 MC1 turns OFF at an inverter fault.
*7 When Pr.138 = "0 (electronic bypass invalid at a fault)", MC2 is OFF. When Pr.138 = "1 (electronic bypass valid at a fault)", MC2 is ON.
