MR-J4-B-RJ020 Standard Wiring Diagram Example
Notes: 1. For details such as setting the controllers, refer to programming manual or user's manual for the controllers.
2. Connections for the second and following axes are omitted.
3. Up to 8 axes are connectable by setting the axis selection rotary switch (SW1).
4. This is for sink wiring. Source wiring is also possible.
5. Create a circuit to turn off EM1 (Forced stop) when the main circuit power is turned off to prevent an unexpected restart of the servo amplifier.
6. Provide an external power supply of 24 V DC ± 10% (required current capacity: 0.1 A) to the interface.
7. SW2 is not for use in the J2S compatibility mode.
8. The total length of the SSCNET cables must be 30 m or shorter. It is recommended that three or four data line filters in serial connection or a cable cramp be used near the
connector on the controller to improve noise immunity.
9. The SSCNET cables vary depending on the controller. Select the appropriate SSCNET cable as follows:
 •A171SHCPU(N)/A172SHCPU(N)/A173UHCPU/A1SD75M:MR-J2HBUS_M-A •QD75M:MR-J2HBUS_M
 •Q172CPU(N):Q172J2BCBL_M(-B) •Q173CPU(N):Q173J2B_CBL_M
 •MR-J4-_B_-RJ020+MR-J4-T20:MR-J2HBUS_M
10. Use setup software (MRZJW3-SETUP161E) when using MR-J4-_B_-RJ020 servo amplifier in the J2S compatibility mode.
Setup software (MRZJW3-SETUP161E) is available for free download. Contact your local sales office for more details.
11. This standard wiring diagram is common for 200 V AC, 100 V AC and 400 V AC type servo amplifiers.
