3. SIGNALS AND WIRING
3 - 16
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) 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 will malfunction and will not output
signals, disabling EM2 (Forced stop 2) and other protective circuits.
3. The forced stop switch (normally closed contact) must be installed.
4. Supply 24 V DC ± 10% to interfaces from outside. The total current capacity is up to 500 mA. 500 mA is the value applicable
when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section
3.9.2 (1) that gives the current value necessary for the interface. The 24 V DC power supply can be used both for input signals
and output signals.
5. When starting operation, always turn on EM2 (Forced stop 2), LSP (Forward rotation stroke end) and LSN (Reverse rotation
stroke end). (Normally closed contact)
6.
ALM (Malfunction) turns on in normal alarm-free condition. (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 [Pr. PD03] to [Pr. PD22]. (Refer to section 3.6.1
(5).)
9. Use SW1DNC-MRC2-_. (Refer to section 11.7.)
10. Controller or parameter units can also be connected via the CN3 connector, enabling RS-422/RS-485 communication. Note
that using the USB communication function (CN5 connector) prevents the RS-422/RS-485 communication function (CN3
connector) from being used, and vice versa. They cannot be used together.

11. When not using the STO function, attach the short-circuit connector came with a servo amplifier.
12. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
13. Plus and minus of the power of source interface are the opposite of those of sink interface.
