3. SIGNALS AND WIRING
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked ) 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 and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. When starting operation, always connect the emergency stop (EMG) and forward rotation stroke end (LSN), reverse rotation stroke
end (LSP) with VIN. (Normally closed contacts)
5. Trouble (ALM) is connected with VIN in normal alarm-free condition. When this signal is switched off (at occurrence of an alarm),
the output of the controller should be stopped by the sequence program.
6. When connecting the personal computer together with monitor outputs 1, 2, use the branch cable (MR-E3CBL15-P). (Refer to
section 13.1.3)
7. The pins with the same signal name are connected in the servo amplifier.
8. This length applies to the command pulse train input in the open collector system. It is 10m or less in the differential line driver
system.
9. Use MRZJW3-SETUP154E of 154C.
10. 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.
