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 forced stop switch (normally closed contact) must be installed.
4. Supply 24VDC 10% 150mA current for interfaces from the outside. 150mA 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 4.8.2 (1) that gives the current
value necessary for the interface.
5. When starting operation, always turn on forced stop (EMG) and Forward/Reverse rotation stroke end (LSP/LSN). (Normally
closed contacts).
6. Malfunction (ALM) turns on in normal alarm-free condition. (Normally
closed contacts)
7. Use MRZJW3-SETUP 211E.
8. Personal computers or parameter modules can also be connected via the CN3 connector, enabling RS-422 communication.
Note that using the USB communication function (CN5 connector) prevents the RS-422 communication function (CN3
connector) from being used, and vice versa. They cannot be used together.
