Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal of the (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 forced stop switch (normally closed contact) must be installed.
4. Supply 24VDC±10% 200mA current for interfaces from the outside. 200mA 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 the forced stop (EM1). (Normally closed contact)
6. Trouble (ALM) turns on in normal alarm-free condition. (Normally closed contact)
7. The pins with the same signal name are connected in the servo amplifier.
8. Use MRZJW3-SETUP221E (Software version C4 or later).
9. For sink I/O interface. For source I/O interface, refer to section 3.8.3. However, pin 23 and pin 25 cannot be used at the source
interface.
10. The assigned signals can be changed using parameter No. PD02, PD04, PD06, PD08, PD10, PD12, or PD14.
11. The assigned signals can be changed using parameter No.PD15 to PD18.
12. The forward rotation stroke end (LSP) and the reverse rotation stroke end (LSN) automatically switch ON if not assigned to the
external input signals.
13. Set " 24 " in parameter No. PD16 to assign travel completion (MEND).
