When using a separate power supply for the control circuit, remove the jumpers connected to terminals R1/L11 and S1/L21.
*2
To use the power failure time deceleration-to-stop function, remove the jumpers connected to terminals R1/L11 and S1/L21, and connect terminal
R1/L11 and the terminal P/+ bus bar and terminal S1/L21 and the terminal N/- bus bar. Pass wires between the converter unit and the inverter
and through the rubber bush on the side face of the converter unit to the terminals inside. (Refer to

The function of these terminals can be changed using the Input terminal function selection (Pr.178, Pr.187, Pr.189).
*4
The function of these terminals can be changed using the Output terminal function selection (Pr.195).
*5
The function of these terminals can be changed using the Output terminal function selection (Pr.190 to Pr.194).
*6
For manufacturer. Do not use.
*7
To use the RDA signal of the converter unit, select the normally-closed contact input specification for the input logic of the MRS signal or X10
signal of the inverter.
To use the RDB signal of the converter unit, select the normally-open contact input specification for the input logic of the MRS signal or X10 signal
of the inverter.
(For changing the input logic, refer to the Instruction Manual of the inverter.)
