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 and other protective circuits.

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

4.When a personal computer is connected for use of the test operation mode, always use the maintenance junction card (MR-J2CN3TM) to enable the use of the forced stop (EM1). (Refer to section 12.1.5)

5.CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the connectors will lead to a fault.

6.The sum of currents that flow in the external relays should be 80mA max.

7.When starting operation, always connect the forced stop signal (EM1) and SG. (Normally closed contacts) By setting “0001” in parameter No.23, the forced stop signal can be made invalid.

8.When connecting the personal computer together with monitor outputs 1, 2, use the maintenance junction card (MR-J2CN3TM). (Refer to Section 12.1.3.)

9.Use MRZJW3-SETUP121E.

10.Use the bus cable at the overall distance of 30m(98.4ft) or less. In addition, to improve noise immunity, it is recommended to use a cable clamp and data line filters (three or four filters connected in series) near the connector outlet.

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

12.Up to eight axes (n 1 to 8) may be connected. The MR-J2S- B/MR-J2-03B5/MR H-BN servo amplifier may be connected on the same bus.

13.Always insert the termination connector (MR-A-TM) into CN1B of the servo amplifier located at the termination.

14.The bus cable used with the SSCNET depends on the preceding or subsequent controller or servo amplifier connected. Refer to the following table and choose the bus cable.
