3 SIGNALS AND WIRING
3.2 Example I/O signal connections
*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 Install a forced stop switch (normally closed contact).
*4 Supply 24 V DC ± 10 % to interfaces from outside. The total current capacity of these power supplies is 500 mA maximum. The
amperage will not exceed 500 mA when all I/O signals are used. Reducing the number of I/O points decreases the current capacity. For
the amperage required for interfaces, refer to the following.

Although the diagram shows the input signal and the output signal each using a separate 24 V DC power supply for illustrative purposes,
the system can be configured to use a single 24 V DC power supply.
*5 When starting operation, turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end), and LSN (Reverse rotation stroke end)
(normally closed contact).
*6 If no alarm is occurring, ALM (Malfunction) is on (normally closed contact).
*7 The pins with the same signal name are connected in the servo amplifier.
*8 TLA will be available when TL (External torque limit selection) is enabled with servo parameters ([Pr. PD03] to [Pr. PD22]).

MR-J5 User's Manual (Function)
*9 Use SW1DNC-MRC2-_.
*10 If not using the STO function, attach the short-circuit connector that came with the servo amplifier.
*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 For source interfaces, the positive and negative outputs of the power supply are reversed as compared with sink interfaces.
