Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal of the (terminal marked
) driver to the
protective earth (PE) of the control box.
2. Connect the diode in the correct direction. If it is connected reversely, the driver 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.
6. The pins with the same signal name are connected in the driver.
7. Use LEC-MRC2E (Ver.1.52E or later).
8. This diagram is for 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.PD03 to PD14.
10. The assigned signals can be changed using the settings of parameter No.PD15 to PD18.
11. Encoder Z-phase pulse will correspond to the differential line driver system and the open collector system.
If the encoder Z-phase pulse is open collector method, it supports only to the sink (NPN) type interface. It does not correspond
to the source (PNP) type interface.
