*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 If the controller does not have the forced stop function, 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 You can change the devices of these pins with servo parameters ([Pr. PD03] to [Pr. PD05]).
*7 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.
*8 If not using the STO function, attach the short-circuit connector that came with the servo amplifier.
*9 Supply 24 V DC  10 % to interfaces from outside. The total current capacity of these power supplies is 300 mA maximum. The
amperage will not exceed 300 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 the input signal and the output signal for convenience. However, they
can be configured by one.
*10 If no alarm is occurring, ALM (Malfunction) is on (normally closed contact).
*11 The pins with the same signal name are connected in the servo amplifier.
*12 You can change the devices of these pins with servo parameters ([Pr. PD07] to [Pr. PD09]).
*13 If installing an external brake mechanism for a linear servo motor or direct drive motor, use MBR (Electromagnetic brake interlock).
