Notes:
1. The total length of the MR-J2HBUSMM-A and MR-J2HBUSMM cable must be kept to within 30m. Use of a cable clamp or data line filter (three or four connected in serial) near the
connector lead-out port is recommended to increase the noise resistance.
2. Refer to “MOTION CONTROLLER Q SERIES (L(NA)03014)” for details on the cable connected between Q172/Q173 and the amplifier.
3. The motor side connections for the second and following axes are omitted from the above diagram.
4. Up to eight axes (n=1 to 8) can be connected. The MR-HMBN type servo can also be connected to the same bus. (Note that the cable differs in this case.)
5. CN1A, CN1B, CN2 and CN3 are all the same shape. Connecting them wrong can cause damage.
6. Always connect the servo amplifier protection ground (PE) (for preventing shocks) to the control box’s protection ground (PE).
