Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal 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. CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the connectors will lead to a fault.
4. The sum of currents that flow in the external relays should be 80mA max. If it exceeds 80mA, supply interface power from
external.
5. When starting operation, always connect the forward/reverse rotation stroke end (LSN/LSP) with SG. (Normally closed
contacts)
6. Trouble (ALM) is connected with COM in normal alarm-free condition.
7. The pins with the same signal name are connected in the servo amplifier.
8. When using override (VC), make the override selection (OVR) device available.
9. When using analog torque limit (TLA), make the external torque limit selection (TL) devices available.
10. When connecting the personal computer together with monitor outputs 1, 2, use the maintenance junction card (MR-
J2CN3TM). (Refer to section 14.1.6).
11. Use MRZJW3-SETUP 151E.
12. When using the internal power supply (VDD), always connect VDD-COM. Do not connect them when supplying external
power. Refer to section 3.6.2.
