2. SIGNALS AND WIRING
Note 1 To prevent an electric shock, always connect the protective earth (PE) terminal (
(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
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.
7. The wiring of the second and subsequent axes is omitted.
8. Up to eight axes (n
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) of the MR-J3- B
Servo Amplifier Instruction Manual 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 of the MR-J3- B Servo Amplifier Instruction
Manual.
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 .
