Note 1. In the initial setting, EM2 is assigned to the CN3-10 pin. Set [Pr. PA04] to "0 0 _ _" when assigning EM1.
2. In the initial setting, CALM is assigned to the CN3-11 pin. Set [Pr. PD09] to "_ _ 0 3" when assigning ALM-A.
3. In the initial setting, MBR-C is assigned to the CN3-13 pin. Set [Pr.PD07] to "_ _ 0 0" when assigning Always off.
4. In the initial setting, CINP is assigned to the CN3-24 pin. Set [Pr. PD08] to "_ _ 0 3" when assigning ALM-B.
5. Because the MR-J4W2-_B servo amplifiers do not support analog monitors (MO1 and MO2), LG for MO1 or MO2 is not
assigned. Use CN3-14 for the control common of the encoder output pulses.
DI1-C is assigned to the CN3-1 pin. Because the signal is for MR-J4W3-_B servo amplifier, it does not function for the MR-
J4W2-_B servo amplifier (Always off).
6. MR-J4W2-_B servo amplifier does not support analog monitors (MO1 and MO2). DI2-C is assigned to the CN3-2 pin, and
DI3-C is assigned to the CN3-15 pin. Because the signal is for MR-J4W3-_B servo amplifier, it does not function for the
MR-J4W2-_B servo amplifier (Always off).
