Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked
main circuit power connector (CNP1) 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 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 switch on the forced stop (EM1). (Normally closed contacts)
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 (C4 or later).
9. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
10. The assigned signals can be changed using the settings of parameter No. PD02 to PD14.
11. The assigned signals can be changed using the settings of 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.
