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 300 mA. 300 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 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. 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], [Pr. PD11], [Pr. PD13], [Pr. PD17],
and [Pr. PD19]. (Refer to section 3.6.1 (5).)
9. Use SW1DNC-MRC2-_. (Refer to section 11.4.)
10. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
11. Plus and minus of the power of source interface are the opposite of those of sink interface.
12. The USB communication function and RS-422/RS-485 communication function are mutually exclusive. They cannot be used
together.
