Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked ) of the servo amplifier 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. Trouble (ALM) turns on in normal alarm-free condition. (Normally closed contact)
6. The pins with the same signal name are connected in the servo amplifier.
7. Use MRZJW3-SETUP221E (C4 or later).
8. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
9. The assigned signals can be changed using the settings of parameter No. PD02 to PD14.
10. The assigned signals can be changed using the settings of parameter No. PD15 to PD18.
