3. SIGNALS AND WIRING
Note 1. To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always connect it to the earth (E) of
the control box. (Refer to Section 3.7.)
2. If the controller does not have an emergency stop function, always install a forced stop switch (Normally closed).
3. CN1A and CN1B have the same shape. Wrong connection of the connectors will lead to a fault.
4. When starting operation, always connect the forced stop (EM1) and P24G. (Normally closed contacts) By setting “0001” in
parameter No.23, the forced stop (EM1) signal can be made invalid.
5. 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.
6. The wiring of the second and subsequent axes is omitted.
7. Up to eight axes (n 1 to 8) may be connected. The MR-J2S- B MR-J2-03B5 servo amplifier may be connected on the
same bus.
8. Always insert the termination connector (MR-A-TM) into CN1B of the servo amplifier located at the termination.
9. 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.
