3. SIGNALS AND WIRING

Note 1 To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked ) of the servo amplifier to the

protective earth (PE) of the control box.

2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will be faulty and will not output

signals, disabling the forced stop (EM1) and other protective circuits.

3. If the controller does not have an forced stop (EM1) function, always install a forced stop switch (Normally closed).

4. When starting operation, always turn on the forced stop (EM1). (Normally closed contacts) By setting "

1 " in DRU

parameter No.PA04 of the drive unit, the forced stop (EM1) can be made invalid.

5. Use MRZJW3-SETUP 221E.

6. For the distance between electrodes of SSCNET

cable, refer to the following table.

Cable Cable model name Cable length

Distance between

electrodes

Standard code inside panel MR-J3BUS M 0.15m to 3m

20m

Standard cable outside panel MR-J3BUS M-A 5m to 20m

Long-distance cable MR-J3BUS M-B 30m to 50m 50m

7. The wiring of the second and subsequent axes is omitted.

8. Up to eight axes (n

1 to 8) may be connected. Refer to section 3.13 for setting of axis selection.

9. Make sure to put a cap on the unused CN1A

CN1B.

10. Supply 24VDC

10% 150mA current for interfaces from the outside. 150mA 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 3.7.2 (1) that gives the

current value necessary for the interface.

11. Trouble (ALM) turns on in normal alarm-free condition. When this signal is switched off (at occurrence of an alarm), the output

of the programmable controller should be stopped by the sequence program.

12. The pins with the same signal name are connected in the servo amplifier.

13. The signal can be changed by parameter No.PD07, PD08, PD09.

14. For the sink I/O interface. For the source I/O interface, refer to section 3.7.3.

15. Devices can be assigned for DI1

DI2 DI3 with controller setting. For devices that can be assigned, refer to the controller

instruction manual. The assigned devices are for the Q173DCPU

Q172DCPU Q173HCPU Q172HCPU and QD75MH .
