3 SIGNALS AND WIRING
3.2 I/O signal connection example
*1 To prevent an electric shock, connect the protective earth (PE) terminal (the terminal marked with the symbol) of the servo amplifier
to the protective earth (PE) of the cabinet.
*2 Connect the diode in the correct direction. If it is connected reversely, the servo amplifier may malfunction and not output signals,
disabling protective circuits such as EM2 (Forced stop 2).
*3 If the controller does not have the forced stop function, always install a forced stop 2 switch (normally closed contact).
*4 When starting operation, turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end), and LSN (Reverse rotation stroke end)
(normally closed contact). If FLS (Upper stroke limit) and RLS (Lower stroke limit) are used via a controller, wiring LSP and LSN is
unnecessary. In that case, set [Pr. PD41].
*5 Use SW1DNC-MRC2-_.
*6 Supply 24 V DC ± 10 % to interfaces from outside. The total current capacity of these power supplies is 350 mA maximum for the MR-
J5W2-_G, and 450 mA at maximum for the MR-J5W3-_G.
The amperage will not exceed 350 mA (MR-J5W2-_G) and 450 mA (MR-J5W3-_G) when all I/O signals are used. The current capacity
can be decreased by reducing the number of I/O points. For the amperage required for interfaces, refer to the following.

The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they can be
configured by one.
*7 If no alarm is occurring, CALM (AND malfunction) is on (normally closed contact).
*8 In the initial setting, CINP (AND in-position) is assigned to this pin. You can change the devices of this pin with [Pr. PD08].
*9 You can change the devices of these pins with servo parameters ([Pr. PD07] and [Pr. PD09]).
*10 You can change the devices of these pins with servo parameters ([Pr. PD03] to [Pr. PD05]).
*11 To prevent an unexpected restart of the servo amplifier, configure a circuit that turns off EM2 when the main circuit power supply is
turned off.
*12 If not using the STO function, attach the short-circuit connector that came with the servo amplifier.
*13 This pin is not available for MR-J5 2-axis servo amplifiers.
*14 This is for MR-J5W3-_G servo amplifiers.
*15 This signal cannot be used for the MR-J5W3-_G.
*16 If installing an external brake mechanism for a linear servo motor or direct drive motor, use MBR (Electromagnetic brake interlock).
