3. SIGNALS AND WIRING
Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked
) of the 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. When starting operation, always switch on the forced stop (EM1) or the forward/reverse rotation stroke end (LSP, LSN).
(Normally closed contacts)
6. Trouble (ALM) turns on in normal alarm-free condition. When this signal is switched off (at occurrence of an alarm), the output
of the programmable logic driver should be stopped by the sequence program.
7. The pins with the same signal name are connected in the driver.
8. This length applies to the command input pulses in the open collector system. The wirings can be extended up to 10m when
using positioning modules with the differential line driver system.
9. Use LEC-MRC2E(Ver.1.52E or later).
10. This diagram is for sink I/O interface. For source I/O interface, refer to section 3.8.3.
11. The assigned signals can be changed using the settings of parameter No.PD03 to PD14.
12. The assigned signals can be changed using the settings of parameter No.PD15 to PD18.
13. Select the number of I/O points of the programmable logic drivers in accordance with the system.
14. It is COM0 for FX
3U
-16TM/ES.
15. It is COM4 for FX
3U
-16TM/ES.
16. If the command pulse train input is open collector method, it supports only to the sink (NPN) type interface.
It does not correspond to the source (PNP) type interface.
17. 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.
