4. SIGNALS AND WIRING
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. Use MRZJW3-SETUP 152E.
9. The signals are not yet assigned in the shipment status.
