Forward rotation start
Reverse rotation start
(Note 5) Forward rotation stroke end
Reverse rotation stroke end

Note: 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked
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 and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. The sum of currents that flow in the external relays should be 80mA max. If it exceeds 80mA, supply interface power from
external.(Refer to Section 3.6.2)
5. When starting operation, always connect the emergency stop signal (EMG) and forward/ reverse rotation stroke end signal
(LSN/LSP) with SG. (Normally closed contacts)
6. Trouble (ALM) is connected with COM in normal alarm-free condition.
7. When connecting the personal computer together with monitor outputs 1, 2, use the branch cable (MR-E3CBL15-P). (Refer to
Section 13.1.3)
8. The pins with the same signal name are connected in the servo amplifier.
9. Use MRZJW3-SETUP 154E.
10. Connect the external 24VDC power supply if the output signals are not used.
