3. SIGNALS AND WIRINGNote 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 outputsignals, disabling the emergency stop (EMG) and other protective circuits.3. The emergency stop switch (normally closed contact) must be installed.4. CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the connectors will lead to a fault.5. The sum of currents that flow in the external relays should be 80mA max. If it exceeds 80mA, externally supply 24VDC 10%,200mA power for the interface. 200mA is a value applicable when all I/O signals are used. Reducing the number of I/O pointsdecreases the current capacity. Refer to the current necessary for the interface described in section 3.6.2. Connect the external24VDC power supply if the output signals are not used.6. When starting operation, always turn on emergency stop (EMG) and forward/reverse rotation stroke end (LSP/LSN). (Normallyclosed contacts)7. Trouble (ALM) turns on in normal alarm-free condition. When this signal is switched off (at occurrence of an alarm), the outputof the programmable controller should be stopped by the sequence program.8. When connecting the personal computer together with analog monitor 1 (MO1) and analog monitor 2 (MO2) on the 7kW or lessservo amplifier, use the maintenance junction card (MR-J2CN3TM). (Refer to section 13.1.5)9. The pins with the same signal name are connected in the servo amplifier.10. This length applies to the command pulse train input in the differential line driver system.It is 2m (6.5ft) or less in the opencollector system.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 3.6.2.13. This connection is not required for the AD75P. Depending on the used positioning module, however, it is recommended toconnect the LG and control common terminals of the servo amplifier to enhance noise immunity.14. For the 11kW or more servo amplifier, Analog monitor 1 (MO1) and Analog monitor 2 (MO2) are replaced by CN4.CN4124MO1MO2LGAA2m (6.5ft) or less3 - 5
