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 (EMG) and other protective circuits.
3. The emergency stop switch (normally closed contact) must be installed.
4. Supply 24VDC 10% 300mA current for interfaces from the outside. 300mA is the value applicable when all I/O signals are
used. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.8.2 (1) that gives the
current value necessary for the interface.
5. When starting operation, always turn on emergency stop (EMG) and forward/reverse rotation stroke end (LSP/LSN). (Normally
closed contacts)
6. Trouble (ALM) turns on in normal alarm-free condition.
7. The pins with the same signal name are connected in the servo amplifier.
8. By setting parameters No.PD03 to PD08, PD09 to PD12 to make TL available, TLA can be used.
9. Use MRZJW3-SETUP 211E.
10. RS-422 can also be used to connect the servo amplifier and personal computer.

11. Use an external power supply when inputting a negative voltage.
12. For the sink I/O interface. For the source I/O interface, refer to section 3.8.3.
