For sink I/O interface
*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. The current capacity can be decreased by reducing the number of I/O
points. For the amperage required for interfaces, refer to the following.

Page 76 Digital input interface DI-1
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.
*5 If no alarm is occurring, ALM (Malfunction) is on (normally closed contact).
*6 The pins with the same signal name are connected in the servo amplifier.
*7 Use SW1DNC-MRC2-_.
*8 If not using the STO function, attach the short-circuit connector that came with the servo amplifier.
*9 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.
