*1 To prevent an electric shock, connect the protective earth (PE) terminal (the terminal marked with the
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.
Page 96 Digital input interface DI-1
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 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.
*10 For source interfaces, the positive and negative outputs of the power supply are reversed as compared with sink interfaces.
