3. SIGNALS AND WIRING
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked with
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. If the controller does not have a forced stop function, always install the forced stop 2 switch (normally closed contact).
4. When starting operation, always turn on EM2 (Forced stop 2). (normally closed contact)
5. Use SW1DNC-MRC2-_. (Refer to section 11.4.)
6. Use SSCNET III cables listed in the following table.
7. The wiring after the second servo amplifier is omitted.
8. Up to 16 axes of servo amplifiers can be connected. The number of connectable axes depends on the controller you use.
Refer to section 4.3.1 for setting of axis selection.
9. Make sure to cap the unused CN1B connector.
10. Supply 24 V DC ± 10% to interfaces from outside. The total current capacity of these power supplies must be 300 mA or lower.
For the servo amplifiers manufactured in April 2016 or earlier (or manufactured in China in May 2016 or earlier), the total
current capacity must be 100 mA or lower. The current capacity 300 mA is 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 3.8.2 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.
11. You can change devices of CN3-13, CN3-9, and CN3-15 pins with [Pr. PD07], [Pr. PD08], and [Pr. PD09]. No device is
assigned to CN3-9 and CN3-15 pins by default. Set [Pr. PD08] or [Pr. PD09] to "_ _ 0 3", and assign ALM (Malfunction) to a
pin of the CN3 connector.
12. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
13. You can change devices of CN3-2, CN3-12, and CN3-19 pins with [Pr. PD03], [Pr. PD04], and [Pr. PD05]. When using
external input signals (FLS, RLS, and DOG) of the servo amplifier with a controller, assign devices to CN3-2, CN3-12, and
CN3-19 pins. No device is assigned to these pins by default. For devices that can be assigned, refer to the controller
instruction manual.
14. The CN3-2, CN3-9, CN3-12, CN3-15, and CN3-19 pins are available with servo amplifiers having software version C5 or later,
and manufactured in May 2016 or later. For the servo amplifiers manufactured in China, these pins have been available from
the June 2016 production. Use MR Configurator2 with software version 1.60N or later.
