(A) Application parameters

Be careful of the capacity of the sequence output terminals.
The applied terminals differ by the settings of Pr.190 to Pr.196 (Output terminal function selection).
Open collector output of inverter (RUN, SU, IPF, OL, FU) 24 VDC 0.1 A
Inverter relay output (A1-C1, B1-C1, A2-B2, B2-C2)
Relay output option (FR-A8AR)

When connecting a DC power supply, insert a protective diode.
When connecting an AC power supply, use the relay output option (FR-A8AR) and use contact outputs.

The applied terminals differ by the settings of Pr.180 to Pr.189 (Input terminal function selection).

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
• Use the electronic bypass function in External operation mode. In addition, the wiring terminals R1/L11 and S1/L21 must be
connected to a separate power source that does 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)

Set "95" and "96"
X95/X96 in any of Pr.180
to Pr.189.

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.

When the MRS signal is OFF, neither the commercial power supply operation nor the inverter operation can be performed.

The CS signal operates only when the MRS signal is ON.

STF (STR) operates only when the MRS and CS signals are both ON.

The RES signal can be used for reset input acceptance with Pr.75 Reset selection/disconnected PU detection/PU stop selection. When
RES signal and another input signal are simultaneously input, the MC operation by the RES signal has a higher priority.

MC1 turns OFF at an inverter fault.

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.

MC operation
: MC-ON
: MC-OFF
-: During inverter operation, MC2-OFF, MC3-ON
During commercial power supply operation, MC2-ON, MC3-OFF
Invariance: The status before changing the signal ON or OFF is held.
