18. MR-J4W2-0303B6 SERVO AMPLIFIER
18 - 24
Note 1. To prevent an electric shock, always connect the CNP1 noiseless grounding terminal (
marked) of the servo amplifier to the
grounding terminal 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 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.
Cable
Cable model
Cable length
Standard cord inside
cabinet
MR-J3BUS_M
0.15 m to 3 m
Standard cable
outside cabinet
MR-J3BUS_M-A
5 m to 20 m
Long-distance cable
MR-J3BUS_M-B
30 m to 50 m
7. The wiring after the second servo amplifier is omitted.
8. Up to 64 axes of servo amplifiers can be connected. The number of connectable axes depends on the controller you use.
Refer to section 18.5 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 is up to 250 mA.
250 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 3.8.2 (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. The
24 V DC power for I/O signal, use power other than 24 V DC power of servo amplifier control circuit power supply.
11. CALM (AND malfunction) turns on in normal alarm-free condition. (Normally closed contact)
12. In the initial setting, CINP (AND in-position) is assigned to the pin. You can change devices of the pin with [Pr. PD08].
13. You can change devices of these pins with [Pr. PD07] and [Pr. PD09].
14. Devices can be assigned for these signals with controller setting. For devices that can be assigned, refer to the controller
instruction manual. The following devices can be assigned for R_MTCPU, Q17_DSCPU, RD77MS_, and QD77MS_.
15. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
