3. 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 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 points
decreases the current capacity. Refer to the current necessary for the interface described in section 3.6.2. Connect the external
24VDC power supply if the output signals are not used.
6. Trouble (ALM) turns on in normal alarm-free condition.
7. When connecting the personal computer together with analog monitor 1 (MO1) and analog monitor 2 (MO2) on the 7kW or less
servo amplifier, use the maintenance junction card (MR-J2CN3TM). (Refer to section 13.1.5)
8. The pins with the same signal name are connected in the servo amplifier.
9. Use MRZJW3-SETUP 151E.
10. 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.
11. Use an external power supply when inputting a negative voltage.
12. For the 11kW or more servo amplifier, analog monitor 1 (MO1) and analog monitor 2 (MO2) are replaced by CN4.
