Example I/O signal connections

Precautions
• Do not connect CN1A and CN1B connectors to a network other than the network used by this servo amplifier. Doing so
may cause a malfunction.
• In the torque mode, EM2 functions the same as EM1.

*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 Supply 24 V DC ± 10 % to interfaces from an external source. 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 35 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.
*9 If no alarm is occurring, ALM (Malfunction) is on (normally closed contact).
*10 The pins with the same signal name are connected in the servo amplifier.
*11 You can change the devices of these pins with servo parameters ([Pr. PD07] to [Pr. PD09]).
*12 When not using the CN1A, CN1B, or CN3 connector, cover them with the supplied cap.
*13 For source interfaces, the positive and negative outputs of the power supply are reversed as compared with sink interfaces.
